Question: Give an example of a question that could be answered by a manufacturer using a hypothesis test. (Remember, if all the data are available, don’t use a hypothesis test. For example, if you wanted to know whether Company X produced more widgets in 2007 than in 2006, you could probably find the records for each year and compare them—so a hypothesis test wouldn’t be necessary. However, if you wanted to find out whether employees of a very large company preferred an increase in salary or an increase in benefits, it would probably be reasonable to survey a sample in order to test your hypothesis.)
