A bank manager is interested in knowing if their bank is not as busy as a competitive bank. They take a sample of 50 days from their bank and a sample of 60 days from the second bank and analyze the number of transactions that took place each day. They find that the variance of the number of transactions at their bank is equal to 795.19 and the second bank's variance is equal to 1,828.56. Let alpha be .05. What are the hypotheses? What is the test statistic and p value?

A city manager wants to know whether less than 25 secretaries are being used per day. If in a random sample of 60 days, the mean number of temporary secretaries employed is 23.5, with a standard deviation s=6.1, is there at the .05 level of significance sufficient evidence to reject the null hypothesis that M(mule)=25? 1.

A sample of 9 days over the past six months showed that a dentist treated the following numbers of patients: 22, 24, 21, 19, 15, 21, 24, 18, and 27. If the number of patients seen per day is normally distributed, would an analysis of these sample data reject the hypothesis that the variance in the number of patients seen per day is equal to 10? Use a .10 level of significance. State the null and alternative hypotheses. 0:  2 Selectgreater...

A social psychologist is interested in whether warmer temperatures influence aggressive behavior. She had 60 people take part in an experiment in which she randomly split participants in two equal groups. In one group, the participants had to complete a frustrating cooperative puzzle together in a very warm room. In the second group, participants completed the same frustrating cooperative puzzle, but the room was much cooler. In both experiments the number of aggressive acts were counted. Data from the experiment...
