A null hypothesis is what is being tested. Essentially, when one runs a statistical test, the objective of the test is to prove the null hypothesis. If the null hypothesis is not proved, then the alternative hypothesis is proved. A good example of this would be trying to test drinking water from a well to prove that it is safe. Let's say that the cutoff for safety is 100 parts per million of a specific element. We cannot tell by looking at it whether or not the water is safe, so we must test it. The null hypothesis is that the water is safe; in other words the null hypothesis is that the water will have under 100 ppm of the element. We run the test on the water and it shows 140 ppm.
This means that the null hypothesis was not proven -- the 140 ppm is higher than 100pm and the null hypothesis was...
As a result, the alternative hypothesis has been proven. The alternative hypothesis is that the water is not safe. We can set the null hypothesis to anything that makes sense -- the alternative hypothesis is essentially the opposite of that. It is important to remember, however, that the scenario must fit. The null and alternative hypotheses must be mutually exclusive and they must be the only two options available -- otherwise rejecting the null hypothesis would not prove the alternative hypothesis.
With statistical techniques, the actual numbers could be quite a bit more complicated, but the underlying principle of the null and alternative hypotheses is the same. The null hypothesis is what we are testing for. If we do not find it, then we cannot accept the null hypothesis and we…
Restaurant Management Challenges involved in restaurant management Restaurants are businesses that offer foods and drinks to customers within the hospitality industry. There is a small distinction between restaurants and hotels in the hospitality industry. Few restaurants expand their business to offer other services that are usually for hotels such as accommodation services. A number of hotels also offer restaurant-related services.

One of the things that will make a difference for the customers is represented by the quality of the food, which needs to be fresh, first and foremost, and tasty. The good quality of the food also refers to how tasty the dishes are.. From this point-of-view, it is highly important for the restaurant to have a skilled chef. The recipes that the restaurant offers can represent an important opportunity.
According to Brech, these trends do not leave much time -- or money -- available for dining at full-service restaurants. In this study, the respondents "reported their families ate at cafeterias, family or chain restaurants, or fine dining restaurants only once or less each week" (Brech 1998: 21). This is not to say, though, that the number of full-service restaurants in countries such as the United States has declined
Management must also alter the overall company culture and corporate environment. In order to effectively do so, management must communicate its vision, goals, and objectives to all stakeholders involved. By communicating this vision, management can ensure that all stakeholders are aware of the new objectives and the importance of each. In essence, management is enlisting others in a common vision by combining common aspirations (1). Through this means management
