Therefore, age does not effect the current sales number as any employee on staff with age as a non-factor is able to lead in the current sales figures.
4. The following is a regression model depicting the likelihood of buying a new car given total family income and the likelihood of buying tickets to a rock concert given age.
a.) Y^ = a^ + ss^X; Y^ = 3.5 + .7X, where Y^ = likelihood of buying a new car and X = total family income
b) Y^= a^ + ss^X; Y^= 3.5 - .4x, where Y^ = the likelihood of buying tickets to a rock concert and X = age.
The regression equation for a is a predictor of Y^ pronounced Y-hat suggests that for every unit increase in x, or family income, y increases by 4.2. So for every increase in total family income the likelihood of buying a new car increases by 4.2.
The regression equation for b is a predictor of Y^ and suggests that for every unit increase in x, or age, y increases by 3.9. For every unit increase in age, the likelihood of buying tickets to a rock concert increases by 3.9.
The ANOVA summary table is the result of a regression of sales on year of sales
Explained by regression 605, 370, 750 1-3.12 with the sum of squares, degrees of freedom, mean, and f-value shown respectively. Unexplained by the regression is 1,551,381,712 8 193,922, 714 and the total error is 9. The alpha value to test whether the relationship is statistically significant is alpha=.05 or 5% so the test is for 95% confidence or that the distribution is within 2?. Yes the test is significant at alpha .05 and does not need to test at alpha .01 however if one does not feel .05 is sufficient then testing at 3? is the next step.
6. A metropolitan economist attempts to predict the average total budget for retired couples in Phoenix based on the average of U.S. urban retired couples total budget. An r squared value of .7824 is the result of the analysis. This is to say that 78% of the data is explained by the dependant variable, or that 78% of the result is explained by the choice in dependant variable. A value above .8 would be a nice target but .78 is very close and therefore suggests that much of the data has been explained by using the mean of U.S. urban retired couples. The result would suggest that perhaps Phoenix may have to lower the predicted average of total budget required as the unexplained 21 and a fraction may imply...
A football teams season ticket sales, percentage of games won, and active alumni for the years 1992-2000 are given below:
The regression equation for sales and percentages of games won is
Y^ = 10528.34+3.48x
The regression equation for sales and number of active alumni is
Y^ = 8112.18+0.76x
8. No the testing of Liker-scaled items without first testing for their linear relationships brings in a measure of multi-collinearity and bias into the study. Additionally, the ethical nature of making decisions that may be use to discipline employees is critical to the operating ethically in a performance measurement environment. This may overstate the frequency of absenteeism or misinterpret the underlying assumptions and lead to a wrong decision or a misinformed decision.

Abraham Maslow and His Contributions to Psychology: Humanistic Psychology Holistic-Dynamic Personality Theory Abraham Maslow is often thought of as the father of Humanistic Psychology and is credited with the inception of theory that departed from the traditional psychoanalytic approach and the behavioral models. With in this paper Maslow's life is addressed as a source of his inspiration for theory, humanistic psychology is defined and Maslow's holistic-dynamic personality theory is given paramount focus.

Compare and Contrast Paper on Abraham Lincoln on Leadership Introduction Successful leadership, like any other endeavor, can be replicated. The recipe for such replication is the study and understanding of the leadership ideologies and approaches of successful leaders in the field of interest. One of the greatest leaders of modern civilization is Abraham Lincoln, and his method, life, and ideologies have been studied and proposed across multiple books and journals of leadership
In return, Lincoln denounced Garrison and other abolitionists as "zealots" who would destroy the Union and dismantle the constitution for their cause. In summary, DiLorenzo challenges the very foundations of classical Lincoln scholarship. He paints Lincoln as a power-hungry politician who put economic interests of his own group ahead of the interests of the country. He craved dictatorial power and willingly prolonged a bloody war in order to further his
Lincoln and leadership" in the Economist discusses Lincoln's leadership skills, showing how, occasionally, in American -- and general history a leader arose who had unconventional leadership skills and was, indeed, an outsider to the system. Sometimes, in fact -- and extraordinarily as it was -- the outsider was better than the insider: more skilled, knowledgeable. He could see it with a fresh eye. Schumpeter (2012) therefore proposes that it

Reminders to Help Kim & Lyons (2003) report that games can be successfully used to instill and enhance individuals' abilities to succeed in a multicultural firm. Game playing possesses numerous characteristics which could enhance the learning of competencies areas of skills, attitudes and beliefs, and knowledge. Games which include low-risk potential can increase a sense of
Stressing the shackles that slavery could latch to a man's mind, Douglass was given insight into the inherent transgression behind the bondage. And his ability to adopt such a perspective, while easy to underestimate from the distance of over a century, is quite remarkable given the overwhelming social constructions designed to deter that sort of thinking amongst his demographic. One of the more effective messages that he conveyed both
