Hypothesis Testing
Answer each question completely to recieve full credit
There is a new drug that is used to treat leukemia. The following data represents the remission time in weeks for a random sample of 21 patients using the drug.
State the Null Hypothesis
Let XA represent the mean remission time of the new drug and XB the mean remission time of the previous drug, then the null hypothesis states that the eukemia remission times are not significantly different (Ho: XA = XB) between the two drugs.
State the Alternatice Hypothesis
The alternative hypothesis is that the time to remission is significantly different (H1: XA ? XB) between the two drugs.
State the Level of significance
= .01, two-tailed
State the Test Statistic
Z scores
Perform Calculations
Since ? = .01 and this is a two-tailed test, then the value for each tail would be .005. This…
global warming. One of the arguments in favor of this being an issue is that temperatures have increased over time, since humans began burning fossil fuels. There are a number of ways to look at the issue, but one thing that has not received much consideration is that baseline data, which is taken from urban areas, may be skewed by other factors besides anthropogenic global warming. One factor that has not yet been studied is the effect of cloudy days vs. sunny days on the temperature readings. To investigate whether there is any merit to this idea, we need test two hypotheses. The first is whether or not the weather in the region makes a difference to the mean daily temperatures that are recorded. The second is whether or not there has been a change in weather patterns (for example, if the pollution from our cities has brought about more…

ne common assumption in economics is that salary is directly related to quantitatively established aspects of job performance and the quality of one's education and occupation. But is this true of all professions? To take one extreme case to make a larger point, the example of NBA players can be used to see that player's statistics are not necessarily a reflection on what he is accomplishing on the job.

One common assumption in economics is that salary is directly related to quantitatively established aspects of job performance and the quality of one's education and occupation. But is this true of all professions? To take one extreme case to make a larger point, the example of NBA players can be used to see that player's statistics are not necessarily a reflection on what he is accomplishing on the job.
One might assume just as in any other business field, a worker's salary is dependent on his performance but the author of this article "used basic statistics such as minutes per game and points per game to determine" if a player's wages could be explained by actual talents, or if the salaries are more due to non-related job performance aspects such as agent's strengths and weaknesses. (Weeks, 1998) The "hypothesis going into the project was that a player's statistics have a positive affect on his salary. We decided that minutes per game, assists per game, rebounds per game, and points per game were variables that would affect salary in a positive manner. We felt that minutes per game was important in our analysis because we felt the more minutes the athlete played, the more he should earn. Points per game were included as a variable because we thought it to be a measure of the worth of that player to the team. Rebounds and assists are also important in judging the athlete's worth to the team. Our final analysis was that points per game would be the most significant variable." Yet, "through the use of hypothesis testing, we discovered that the model was significant at an alpha of.05. By performing individual tests, we found that the only variable that has a significant positive affect on salary is points per game. From here, one might want to examine the player's popularity, the impact of their agent, the perceived added income they bring to the team, as well as other, qualitative, variables." (Weeks, 1998)
How does this hypothesis affect daily life? Quite simply it shows that salary is not always contingent upon quantitatively established job performance variables, even in a highly numbers related sport. Other, more subjective factors come into play, no pun intended.

Prison GED programs
The General Education Development initialized as GED is a service program of the American Council on Education. The tests in the GED are for measuring the proficiency of the persons taking the test in science, mathematics, writing, social studies and reading (Kaprov & Kaprov, 2009). When the person passes the General Education Development, they acquire a certificate equivalent of the high school certificate credential. This gives the person the chance to enroll in a known university or college to further their skills that enable them to face the world. The tests issued measure the significant knowledge and skills a person can express Van & Salisbury, 2014). This includes the abilities of the person to evaluate, analyze and draw conclusions; and proficiently express ideas…

statistical analysis as well as ensuring the data used is accurate, it is also essential that the appropriate statistical tools are used to undertaken in the analysis. Two similar tests are the t-test and the z-test. In both cases the test is usually applied in a situation where there is a desire to test the means of two samples, or the mean of one sample against a known mean to determine of there is a statistical difference. However, despite the similarities of the purpose of the t-test and the z-test, there are also some differences which mean that the tests are suitable for different types of situation. To appreciate when the different tests should be used, the paper will start buy looking at the z-test, and when it should be used, as well as consider the use of a t-test, which will lead to an understanding of when the less…

Null Hypothesis and an Alternate Hypothesis
Hypothesizing in business assists leadership in deciding which avenue to take for the overall health of the organization. This is done by allowing the business managers to make decisions after having full research. Business leaders have had to employ hypothesizing to facilitate the implementation of right decisions in their lines of duty. This is an important process because organizations are made or destroyed by the nature of decisions that leaders make. Decisions that leaders make in an organization are critical, for they reflect the current and future success of the business. It is on this account that the business leaders work hard to test the hypothesis of different issues in an organization before making the right decisions (Albright, Winston, & Zappe, 2010).

What are the positive aspects of this theory -explain how markets behave? Why?
The positive aspects of this theory are that it identifies changes in the markets early. This helps investors to be able to purchase stocks when everyone has become overly pessimistic (leading to a massive selloff). At the same time, this theory helps to determine when the underlying trends could be changing (with investors becoming overly optimistic). This helps these individuals to reduce their risks and increase the chances of realizing above average returns. (Livingston 2012)
A good example of this occurred in 2008 when the federal government was providing assistance to large financial institutions such as: AIG and Citigroup. At the time, the markets were in a free fall surrounding fears that the issues with housing market will cause a major economic implosion. Moreover, investors were fearful about the possibility of the Big Three Automakers…

Gaia Hypothesis and Daisy World
The development of the Gaia Hypothesis is described with some emphasis on how the concept has evolved in response to other scientist's skepticism. The Gaia concept itself is described and discussed. A possible means for reconciliation of the holistic Gaia hypothesis with reductionist thinking is discussed. I conclude by summarizing what the paper has accomplished.
The Gaia Hypothesis was first published by James E. Lovelock in 1972 (Lovelock, par. 23). It was, at the time, the end product of a series of observations Lovelock had made about Earth, Mars and Venus (Margulis and Lovelock, p. 11(2)).
The premise underlying the Gaia hypothesis is that the entire planet evolves over time because of the interaction of living things with their surrounding environment. Because of the interdependence of the evolution of environment and biome, Lovelock likened the entire planet Earth to a living thing with complex interlocking…

students' absence. My first hypothesis is that the food was contaminated. I base my evidence on the following: Spikes of absence for band class in all four schools fall generally in the middle of the month and towards the ends of the month with a wide outbreak of the flue occurring during that time as well as evidence indicating that the food was improperly cared for.
For at least three schools (Roosevelt, Truman and Jackson) spokes of absence seem to be highest in the Band class particularly around 5/18 (with Jackson showing 33.3 absences on that day, 23.3 and 17.3 on consequent days until gradual reduction is again achieved. In Roosevelt, there are a similar high number of absences on 5/18 with 25.0. Truman's band class shows a huge number of absence on 5/18 (33.3; with 23.3 and 16. 3 on consequent days. Looking at the information on the school…
Abstract
Developing a researchable question is one of the challenging tasks a researcher encounters when initiating a project. In current clinical practice, both unanswered issues or when experiences dictate alternative therapies may provoke an investigator to formulate a clinical research question. This paper describes PICO (population, intervention, control, and outcomes) criteria in framing a research question. Finally, it assesses the characteristics of a peer-reviewed article on urinary tract infections.
Part 1
EBM, shorthand for Evidence-Based Medicine, is a core aspect of the medical profession. EBM provides statistical analyses and matters of clinical concern. It is based on research, reading, analysis, and combining many papers generated within the medical fraternity. EBM applications based on research evidence and clinical knowledge and reviews of the system go a long way in improving clinical decisions. Usually, the PICO guideline is applied in developing a comprehensive, focused definition of clinical concern. In such a system,…
Efficient Market Hypothesis
As previously discussed, the weak form efficiency suggests that share prices should follow a random walk, in that each change in share price is unpredictable based on past information. Formally, this is expressed in the following relationship:
where the variables are independent and identically distributed random variables representing equity prices at times 1,2,3…,k. So X is the equity price, the equity price at a point in time n and the change in equity price at any given time is not explained by the past equity price.
The augmented Dickey-Fuller test considers the following model:
where p is the lag order of the process which can be determined by the examination of autocorrelation and autocorrelation plots, and are the factors determined by the regression. The unit root test has the null hypothesis, and the rejection of the null hypothesis implies that the time series is stationary. The variable…

Behavioral Finance Concept v. Efficient Market Hypothesis:
For more than a century, the concept of efficient markets has been the subject of numerous academic researches and huge debates. An efficient market is described as a market with a large number of balanced profit maximizers that are actively competing against each other to forecast the future market values for individual securities. The efficient market is also defined as a market where current information is nearly freely available and accessible to all participants. Generally, in an efficient market, competition will make complete effects of new information on essential values to be reflected instantly in real prices (Singh, 2010). The efficient market hypothesis has developed to become a significant cornerstone of contemporary financial theory even though the market seems to be more modern and characterized by increased inefficiencies. As a result, the standard finance for rational analysis framework has been placed in an…

This is because, the efficiencies in the market are: providing no kind of leverage to these individuals. At which point, any kind of advantage that they may have would be eliminated. This is important, because it provides good insights, as to how efficient the markets really are. As a result, this is what will reduce the underlying returns every single year. The author is an economist with Oxford University. (urton 2005)
The article that was written by Chen (2005), discusses how the EMH theory can be able to provide the most relevant information surrounding stocks. Yet, when this was compared against computer-based programs, they were able to identify changes in prices at least 50% of the time. This is important, because it is showing how the changes in the expectations for stocks, can be more accurate when using various programs. Once this takes place, it meant that traders and investors…

But few can deny that the Prebisch-Singer is flawed -- as the recent commodity boom in corn demonstrated ("Latin America's Keynes," The Economist, 2009). hile "it is true that real prices have fallen for a large number of commodities in the course of the 20th century" this has not been a continuous trend, certainly not for all commodities and it has proved difficult to forecast the relationships between manufacturing and primary good-producing nations regarding commodities and trade, given the considerable variance exhibited by recent history (Newbald et al. 2005, p. 493).
Nor have all nations that have taken the advice to shift from commodities to manufacturing prospered. One "study observed rapidly rising shares of manufactured and electronic goods in Korea's total exports and a trend decline in Korea's terms of trade" from 1967 -- 2001, but "contrary to the expectation of Prebisch, the increasing proportion of manufactured and electronic goods…

INVERTED U. HYPOTHESIS
It has been established that competitive state-anxiety normally follows a certain pattern of one-sided feelings of anxiety as well as inadequacy that combines with increased arousal of automatic nervous system (Fazey, 2008). Accordingly, the theory of Inverted U. hypothesis was formulated to explain this aspect, and it is widely applied in sports psychology. Inverted U. hypothesis a theory that suggest that there is a relative amount of anxiety and arousal that triggers one to perform higher- extremely little arousal or anxiety and too much arousal or anxiety will lead to poorer performance. This present paper briefly discusses the Inverted U. hypothesis in sports psychology.
Discussion
Until presently, the traditional Inverted theory had been the key model employed by sports psychologists to explain the arousal-performance relationship. Nevertheless, various sport psychology researchers have criticized this relationship, and the modern trend is a change towards a higher multidimensional perspective of…

efficient market hypothesis and its relation to securities prices, their response to new market information, investor opportunities, and behavioral finance challenges.
hat does the efficient market hypothesis say about a) securities prices?
An efficient market is one in which "the market price of a security is an unbiased estimate of its intrinsic value" (Chandra, 2008). That is not to say that the market price for a security will equal its intrinsic value all the time. But what it does say is that there will be errors in market prices but they are not biased; and it does also say that while the price of securities can and will diverge from the intrinsic value of the securities but that deviation will be (in most cases) random. The divergence of the price from the intrinsic value will not be linked "with any observable variable" (Chandra, 422).
Because the deviations of the market…

If they can bench-press heavy weights, they may emphasize athletics at the expense of academics, in terms of how they prioritize their time. However, it is equally possible that in some schools, high-achieving students also use athletics as a way of bolstering their college resume. Factors such as the school, the degree to which athletics makes demands upon student athletes within the particular environment, and the intelligence of the players may indicate there is no correlation.
Daily air temperature & the average weight of clothing worn
H1: There is a negative correlation between temperature and weight of clothing -- in other words, greater the air temperature, the lighter the clothing.
H0: There is no correlation between temperature and weight of clothing.
Estimate: Negative correlation -1
Analysis: The research hypothesis is likely to be proven, with only small variations for such factors as rain and humidity.

Disaster Preparedness
In the second hypothesis of the proposed research project, disaster management and emergency response are critical areas which can be explored further in terms of the United States' current performance in this area, applied in the context of national security. he second hypothesis of the study states that, there is a significant relationship between performance/competence in disaster preparedness and emergency response capabilities and the successful implementation of homeland security in the United States.
o test this hypothesis, the important variables that must be taken into consideration are (1) performance or competence in terms of disaster management and emergency response and (2) successful implementation of homeland security in the U.S. o measure performance or competence in terms of disaster management and emergency response, specific measures that could help determine this variable are the following: competency of individuals in agencies and departments responsible for disaster management and emergency response (on…
This journal article explores the disaster preparedness of the government in terms of a medical emergency response in the event that a disaster or attack (such as the September 11 attack) occurs in U.S. territory. One of the identified issues in medical emergency response is the lack of resources (staff and capacity in hospitals) necessary for an effective emergency response to be implemented in hospitals (i.e., from a medical perspective).

The article discusses the importance of frequent and intensive trainings as an effective mitigation plan in disaster management and emergency response planning. The discussion centers on preparedness in terms of responding to emergencies related to attacks with weapons of mass destruction or WMDs. The model introduced by the author proposed subsistence to the following steps in curtailing or preventing a WMD attack from escalating, such as: establishment of a surveillance system; specific training for health care personnel; and a central federal coordinating office responsible for spearheading an effective emergency response program, which would include the state and local representatives of law enforcement, fire services, emergency managers, and healthcare professionals.
H Hypothesis
The general field of human resources has become more and more difficult as well as more perilous. That is not just a simple generalized statement made for dramatic effect and just for the purpose of setting up the introduction of this paper. Indeed, there are some questions that can and should be posed by human resources professionals that do not have clear answers because of how complicated and how contradictory the field's body of work has become. The ethical implications and obligations pertaining to human resources have been made very muddled by contradicting laws and guidelines thus making real compliance beyond a reasonable doubt very hard to pull off.
The hypothesis that underlies this report comes down to one main statement, and that is as follows:
The different ethics, laws and vagueness that exists in both has made it possible to become completely and reliably compliant with the…

sufficient evidence for its hypothesis or claim?
The paper is clear int hat it provides us with Introduction, body, and conclusion. The theme is simple too: health care providers (the paper tells us) need to respect, acknowledge, and understand the challenges that the 3 religions -- Judaism, Islam, and Shintoism -- can provide to th health care system. The health system needs to know how to satisfy adherents of these religions in order to optimize their medical care.
The paper then goes through a brief description of each religion (in Judaism's case, of Orthodox Jews) particularly as touches on their medical care and cursorily describes how medical practitioners can meet these needs. There are many more points that can be mentioned, particularly in the case of Orthodox Judaism where the profession may be riddled with many more challenges, such as kosher (and food regulation exist with Islam too).

Tips on Understanding and emembering the Three Types of Hypotheses
The three types of hypotheses can seem confusing at first, so it is helpful to devise tips for understanding and remembering their differences. The three hypotheses -- null, nondirectional and directional -- can best be described in the following terse manner: null means no relationship between variables; nondirectional means that there is a relationship or difference between variables but the hypothesis is not concerned with the outcome of the relationship/difference -- only with the fact that the relationship/difference exists; and directions means that the outcome is important to the hypothesis. To put it even more simply, null means no relationship/difference; nondirectional means relationship/difference; directional means outcome of relationship/difference (Elwell, 2013).
The tips to remembering these three types of hypotheses can include spending time examining many different examples of hypotheses and identifying their type. For instance, the resource text provides examples…

Technical Analysis in the Implication of Efficient Market Hypothesis on Silver Market
The thesis is for the study of simple commonly used technical trading rules, which are applied on silver market. It covers years 1989 to 2005. A famous study carried out by Lakonishok, Lebaon and in year, 1992 has clearly shown that technical analysis can lead to abnormal prices when compared with buy-and-hold strategy. Other studies have been carried out and found out that technical trading rules cannot over-rule passive investment management strategy. The study uses Brock et al.'s methodology. Several trading rules are discussed (Dawson & Steeley 2003).

The availability of digital social media has increased the incidence of extramarital affairs by providing a convenient medium for initiating anonymous social overtures.
Digital media have been used extensively to conduct illicit sexual affairs.
The privacy of the medium permits secrecy from spouses and significant others.
The anonymity of digital communications facilitates deception in social overtures.

The case of the Hispanic race was no different from the black Americans'. One of the rapidly increasing minority groups in the country, even surpassing the African-American minority group, Hispanics had experienced similar conditions that made them a colonized minority group. Hispanics demonstrate the characteristics that Blauner argued as illustrative of the African-American experience: firstly, they (Hispanics) belong to the economic periphery and secondly, they become susceptible to greater racial discrimination.
Hispanics are a colonized minority group because they are not given sufficient economic support in the society. Most members of this minority group engage in labor with lower-than-the-minimum wages; this is a result of Hispanics being illegal migrants in the country. As a result of these low incomes, Hispanics move further towards the economic periphery due to lack of opportunities, such as availing proper health services and attaining higher educational attainment.
Apart from becoming part of the socio-economically…

Such a presence can contributes to the media-generated stereotype of the limited aspirational level of the community in the so-called 'white world,' much in the same way that negative portraits of African-Americans create a form of internal colonialization through media fixations upon Black criminals, for example, as opposed to Black civic and professional leaders, although such leaders exist. (Moore, 1997)
The possibility of some community individuals being affected by internal colonialization should not be lightly dismissed, even if some Hispanic communities have been able to counteract its effects with cultural neighborhood pride. Even groups such as immigrant Hispanics, that may vocally manifest strong group pride and idenitification may still, through the process of internal colonialism, assume that whites are more apt to become professionals and to suceed within the context of certain professions. Although much criticized today as self-defeating in nature, Blauner's hypothesis at the time the author first advanced…

In a separate study, researchers at Brandeis University concluded that aging adults with moderate hearing loss may spend cognitive energy on hearing accurately to the extent that their ability to remember spoken language suffers (Medical, 2005).
Although the studies above may have determined that age has some effect on loss of cognitive function, no definitive determination has been made as to whether hearing loss is the cause or simply a part of the reason for loss of cognitive function.
The research proposed will examine the effects of hearing loss on cognitive function regarding verbal recognition and performance of auditory processing. Whether hearing loss in individuals of any age affects their loss of cognitive function will be determined by testing 60 subjects who have experienced hearing loss due to aging or other reasons, compared to a control group of comparable subjects without hearing loss by administering the same test to them.…

External validity concerns "whether results from experiments in one setting (time and place) will be obtained in other settings" (Maxfield and Babbie 122). One external concern is the use of a middle-class suburban neighborhood. If this study was done in an upper-class neighborhood, a rural neighborhood, an urban neighborhood, or a low-income neighborhood, the results might vary greatly. In terms of internal validity, the causality of aggressive video games for aggressive behavior might be difficult to prove given all the other stimuli that can potentially cause aggression in children (including violence in other media like music, television, and film, violent or aggressive living circumstances which may not be disclosed to the researcher, etc.).

Assumptions were made regarding the individual state-level view about the punishment -- it is far more utilitarian to support capital punishment in states that have rising crime rates and proportionally higher rates of murder. Further, because the racial aspect of the death penalty is so controversial, and for some the main focus of the debate, the study measured racial composition in the data as the percentage of nonwhites to the overall state population. Factors regarding levels of urbanization and religion were also factored into the results. Despite these rather rigorous variable sets being included, any sociologist will confirm that cultural factors like urbanization, religiosity, and even political leanings have undergone a massive shift since the 1940s and 1950s; in most cases liberalizing the population factors that approve of the death penalty.
Certainly, this study is both robust and detailed in the sorting and statistical applications run on the data. The…

Management Strategy to Utilize Meta-Analysis Technique for Nuclear Energy and Waste Disposal and Create Social Sustainability
This research proposal explores the link between public perceptions of nuclear power, how those perceptions are formed, and what influence those opinions have on energy policy. These issues are important in light of two realities. First, nuclear energy is declining in its share of global energy. Second, nuclear energy offers what might well be the best solution to climate change. Given the threat posed by climate change, it makes sense that nuclear power would be increasing in share, not decreasing. This esearch proposal seeks to look at some of the issues facing nuclear power, and how it can overcome these issues to increase share going forward.

Ultra violet light affects many people, and several experiments may be done to either support or disapprove the hypothesis. Approval of the hypothesis forms a theory that people who are highly exposed to ultra violet light have higher chances of getting skin cancer. Theories on some scientific approach may serve as sources for theories. Observation of people's behavior may lead to development of hypothesis. This includes looking at how people dress during certain times or what they do at certain times of the year. esults obtained over a research or experiment may lead to development of a theory. Experience of the scientists in their work may be a source of hypothesis and theory. Many things happen around that nobody can explain them scientifically. The scientists come with a hypothesis about something and do numerous tests and observations to know how some things happen Eberhardt, 2003()

Conclusion
Hedge funds are therefore not suitable for investors because they effectively underperform other hedge funds. This fact that there are tighter constraints, stricter regulations as well as lower incentives should deter retail investors from investing in hedge funds. The disadvantages and risks associated with hedge funds makes them unsuitable investment vehicles for retail investors.

Statistical Terms
The author of this report has been asked to answer three broad questions about certain statistical terms and concepts. The first one of those will be standard deviation. The second of the three will be hypothesis testing. The final question will center on standard error and what it means. While statistics may be daunting and intimidating, the concepts and terms used in statistics parlance are not hard to understand or comprehend so long as they are explained and quantified carefully.
The first overall question is what precisely standard deviation happens to be. To put it simply, standard deviation is how dispersed a set of numbers are. For example, the numbers 1, 2 and 3 are very close together so the standard deviation value would be rather small. However, the numbers 1, 1000 and 1,000,000 would have a very large standard deviation because the overall range of the numbers…

Testing
In this week what was interesting in the realm of hypothesis testing is the t-test.
All areas of science make use of t-test. One of the major applications of that t-test is to provide means to research questions. In hypothesis building, it is very important to form correct and factual research questions. Along with the formation, researchers also need to have a broad idea of the possible answers to the hypothesis which can help identify the direction of the research. Sometimes referred to as "Student's t-test," it was named after the person who helped in the study of the distribution of the means from within a small sample way back in 1890. The student was a pseudo name of William Gosset found out that the means are normally distributed only is cases when it is possible to know the actual standard deviation in the population in case of all…

Mason Sexton is trying to renovate the house he inherited located in Charlottesville. The area is a prime location, and with the proposed construction of a multi-storey building, it will attract a good number of tenants. Sexton is not experienced in real estate development, and he has been making calculations based on the research he has carried out. The costings he has come up with are not viable since no financial institution is willing to back his project by offering him a loan. Sexton has managed to carry out most of the investigative, conceptual, and planning stages by himself. However, he runs into problems due to his inexperience in the initial planning stages. He has not managed to obtain funding for the project, and he has to spend money to create the plans and obtain a certificate of occupancy.

Human Trafficking
The goal to eradicate human trafficking in today's modern society is an admirable one, and one that should be attainable. As Gallagher states in a 2011 study "The TVPA lays down minimum standards for the elimination of trafficking as well as detailed criteria for evaluating the performance of states" (Gallagher, 2011, p. 381). Gallagher goes on to compare the TVPA with similar international laws and finds that on an international basis "The international machinery available to expose the many ways in which individuals exploit each other for private profit, to identify government toleration of or complicity in that exploitation and to evaluate national responses is weak and highly compromised" (p. 396). However, the same study determined that most governments are working diligently on a year-to-year basis to up their performance and take seriously the problem of human trafficking, and therefore there is a light at the end of…

Aborigines are Australia's original inhabitants and until the late 1700's -1800's the aborigine had little contact with Western civilization. Local dialects and the territorial nature of bands provided the different social groups their distinctive identity. The Mardudjara (Mardu) aborigines are part of the Western Desert cultural block in Australia (Tonkinson, 1978). The Mardu culture, societal system, etc. has never been recorded in its pristine state as anthropologic researchers did not study the group until well after alien influences had occurred. Nonetheless, the nomadic lifestyle of the Mardu was dictated by the harsh climate in which they live and they are an extremely interesting group. Nomadic groups like the Mardu often have a perception of gender or a cultural gender schema that fits in functionally with their lifestyle and is based on a division of labor and status that allows the group to maintain an identify, clearly defined roles, and survive…

Sustainability
Perceptions of sustainability improved slightly in the experimental group, however this change was not significant and the null hypothesis is not rejected (p=.32). The flag exposure did not improve perceptions of sustainability to a noteworthy degree.
Traditionality
Once more, there was statistically significant change -- and once more, it was so significant that the null hypothesis would be almost certainly rejected (p-value is effectively 0) -- but that this change was again in the wrong direction. Flag perception (or possibly the confounding variable of healthy eating desires, though that seems far less likely for this item) is correlated with a significant decrease in perceptions of traditionality, not an increase as predicted in the alternative hypothesis. The null hypothesis remains in place, therefore.
Conclusion
With one confounding variable between the groups, the examination of the given experimental variable (i.e. The inclusion of the flag on the product image) and its…

Sources of Intelligence. Furthermore, my reasons for conclusions properly describe quality and reliability of underlying sources. I also properly distinguished between underlying intelligence and analyst's assumptions and judgments.
Finally, I used logical argumentation.
To test whether the research results are statistically significant an appropriate test of statistical significance should be run. A chi-square "goodness-of-fit test is used to determine whether a set of proportions have specified numerical values" (Hypothesis testing, 2009, Quick MBA). However, in this specific instance, since it is likely that multiple batch tests for defects will be run, an ANOVA test would be more appropriate: "The primary purpose of ANOVA is to test for differences between multiple means. Whereas the t-test can be used to compare two means, ANOVA is needed to compare three or more means. If multiple t-tests were applied, the probability of a TYPE I error (rejecting a true null hypothesis) increases as the number of comparisons increases" (Hypothesis testing, 2009, Quick MBA). A one-way ANOVA examines whether multiple means differ. "ANOVA calculates the ratio of the variation between groups to the variation within groups" (Hypothesis testing,…

Part-time faculty are likely to be less experienced and uncertain of what standards to apply in grading, and might even want to ensure that their students 'liked' them more, so they could gain a permanent full-time position at an institution. Part-time faculty tend to have less institutional support, such as permanent offices. They may lack university telephone and email accounts, which can facilitate student contact and thus improve ratings.
However, much to Landrum's surprise, the evident dedication of part-time faculty and their high student ratings did not support his hypothesis. Not only do the part-time instructors lack technical support and have less experience teaching, they also "teach a greater proportion of lower-division students compared to full-time faculty, who may be less enthusiastic about the academic process" yet results showed no significant deviation in terms of part-time teacher evaluations or the course grades they awarded to students (Landrum 2009, 24).

Given that hypothesis testing holds the potential to provide keen business insights, the question that immediately arises is 'how does one conducts a hypothesis test?' It is a five step process.
1. First we formulate the null hypothesis (Ho), the statement or claim that will be tested. Using our earlier widget example, the null hypothesis (Ho) would be "Productivity is low in the widget making department because morale is low" (Bushman, 2007).
2. Next we formulate the alternative hypothesis (Ha), the exact opposite of the null hypothesis. The alternative hypothesis (Ha) would be "productivity is unrelated to morale."
3. We then identify a test statistic that can be used to measure the truth of the null hypothesis (more on this shortly).
4. We determine the P-value is the probability of obtaining a test statistic at least as extreme as the one that was actually observed, assuming that the null hypothesis…
To define the safety objectives of the UAV, it is essential to evaluate the current level of safety necessary for the human-piloted aircrafts. While manned pilot aircrafts consider the safety of the pilots and the people on board to be important, however, the safety of the UAV is considered relatively to the hazard that that it will cost to the community. Thus, the intervention of human related aviation safety is still critical to enhance overall safety of the UAV. Although, the UAV accidents may lead to the zero loss of pilot's life, nevertheless, the financial investments that the governments or private organizations provide for the development of the UAV is huge, and the implementation of maximum safety to realize the objective of UAV is very essential. The human related aviation safety is still essential.
The thesis investigates selected human factors affecting safe operation of the Unmanned Aerial Vehicle. The thesis…

This current research developed and tested a model of work engagement contagion in which the organizational citizenship behaviors (OCBs) and competitive behaviors of coworkers influence employees' engagement with their jobs. In a sample of 1,422 departments of an insurance firm, multilevel analysis revealed that coworkers' OCBs and competitive behaviors explain variance in individual work engagement over and above that explained by other individual and group-level predictors. Broadly speaking, these results suggest that coworkers' OCBs and competitive behaviors play critical roles in explaining why people are more engaged with their work. Implications are discussed.
Hypothesis 1: Coworkers' OCB is positively related to work engagement.
Hypothesis 2: Coworkers' competitive behaviors mediate the positive relationship between coworkers' OCBs and focal employee work engagement.
OCB (+1) WORK ENGAGEMENT
OCB (+2) COMPETITVE BEHAVIORS WORK ENGAGEMENT
The OCB's are the independent variables. The employees' competitive behaviors are the mediators. The…

Organizational studies benefits from interaction with other areas of study. The articles and research questions in the paper reflect a curiosity of the connection among media, technology, and behavior. Each article and set of authors approaches this question from a different perspective and in conjunction with another school of thought to help problem solve and with which to cooperate. The paper selects and uses three heuristics as way to explore research questions and hypotheses further and better. The paper substantiates the validity of the proposed research question. The paper also describes the context within which the proposed research would fit.

Abstract:
We argue that because of the important epistemological differences between the fields of information technology and organization studies, much can be gained from greater interaction between them. In particular, we argue that information technology research can benefit from incorporation institutional analysis from organization studies, while organization studies can benefit even more by following the lead of information technology research in taking the material properties of technologies into account. We further suggest that the transformations currently occurring in the nature of work and organizing cannot be understood without considering both the technological changes and the institutional contexts that are reshaping economic and organizational activity. Thus, greater interaction between field of information technology and organization studies should be viewed as more than a matter of enrichment. In the intellectual engagement of these two fields lies the potential for an important fusion of perspectives, a fusion more carefully attuned to explaining the nature consequences of the techno-social phenomena that increasingly pervade our lives.
At which point, workers are either fired or arrested by the police. The subcontractor will then, hire other people to work in the place of employees that are creating problems. Over the course of time, this can cause feelings of animosity inside the community. Moreover, there are no social responsibility practices for these regions. This means that no one is focusing on understanding the social, economic and environmental impact of the company's activities on different areas. Once this occurs, is when there is the possibility that there will be some kind of backlash from these issues. This information is showing how Apple and its third party suppliers are walking a thin line when it comes to their practices in regions such as China. Therefore, this source is supporting the hypothesis that was presented earlier. (Stonebreaker, 2009, pp. 161 -- 177)

Harassment, including sexual and other types as well, is also a common type of formal complaint that must be taken very seriously by contemporary businesses. More extensive employee training can help better inform employees of appropriate work behavior, so that there are less incidences of harassment between employees unknowingly.
etter trained employees makes for a more efficient work environment with less complications. Therefore, the research showed that "many organizations within it industries focus on providing "extensive retraining of employees," especially "as reengineering efforts go forward it is important to define and redefine performance goals and objectives, maintain a strong commitment to the vision, break the barriers between the departments, and be flexible as the business environment changes."
More extensive formal training can help with "nipping negativity before it derails morale" by reassuring the proper procedures but also by explaining appropriate company policy more directly and intimately so that all…

ecession and the Performance of Banking Industry
ecession worked negatively on the banking industry especially so because the industry was still at its initial growth stage. The industry has reformed and change significantly following changes in observed. The data analyzed is expected to show how much recession influenced the changes in policy and regulations. It will also show that banks had a lesson to learn as far as the economic performance and trends were concerned. To date, given the trends banking industry are seen as most susceptible to the economic downturn and the key resolving this is to make changes as a safe guard measures. This is expected to come out in the data analyzed showing the existence of policy and operation changes and strategies adopted in light of economic performance.

Direct Selling
A lot of companies are resorting to marketing one-to-one or concentrating on a narrow niche. For this reason, the respective corporations find it preferable to make use of direct communication with their clients who are typically a small targeted group that are considered after much thought. Direct communication helps the companies in obtaining a quick feedback from the clients that quickens the pace of their decision making. Over the years, the paradigm of direct communication has come a long way because of the dramatic evolutions in technologies and because of the introduction of new marketing media, particularly the usage of Internet.
Direct mailing and electronic catalogs, facilitated by Internet technologies have allowed for the implementation of models related to direct marketing (Jonker, Piersma, & Potharst, 2006; Liao & Chen, 2004; 2011). esearchers in the past have made use of direct communication as a model of complete business or…

Ethics in Criminal Justice:
The police function has continued to be the most needed elements since the beginning of the existence of human societies because social coordination and harmony have never prospered without some kind of supervisory authority. The supervisory authority or power has usually been shared among several agencies or departments including policing. These various departments have been planned and synchronized to provide the service efficiently and effectively. Since its inception, policing have been mandated with the task of identifying and convicting criminals. However, the police have been expected to have an increasingly wider social role in acting as crisis managers or problem busters. As the police have been faced with numerous moral challenges, there are various theories that have been developed to describe ethics within the field of criminal justice.
Slippery Slope and Gratuities:

ANOVA Test
The focus of this proposal is to use the analysis of variance (ANOVA) to test whether the video games influence behavior. There has been a general public concern on the risk factor of video games on the youth's behavior especially children under 18 years of age. Science Daily (2013) shows that video games are the risk factors to aggression and criminal behavior. Despite this assertion, there still a paucity of valid and reliable academic research on the risk factors of video games on behavior. This proposal attempts to fill the gap by using ANOVA to test whether the video games influence behavior.
Do video games influence the aggressive or criminal behavior?
ANOVA is an appropriate statistical test for the proposal because it will be used to test for a significant difference of two means. Using the ANOVA for the proposal, the researcher will be able to produce valid…
