Executives of a supermarket chain are Interested in the amount of time that customers spend in the stores during shopping trips. The mean shopping time, H, spent by customers at the supermarkets has been reported to be 35 minutes, but executives hire a statistical consultant and ask her to determine whether It can be concluded that u is different from 35 minutes. To perform her statistical test, the consultant collects a random sample of shopping times at the supermarkets. She computes the mean of these times to be 39 minutes and the standard deviation of the times to be 12 minutes. Based on this information, answer the questions below. What are the null hypothesis (Ho) and the alternative hypothesis (H) that should be used for the test? Ho: H is (? H: u is ?

Question
Executives of a supermarket chain are Interested in the amount of time that customers spend in the stores during shopping trips. The mean shopping time, p, spent by customers at the supermarkets has been reported to be 35 minutes, but executives hire a statistical consultant and ask her to determine whether it can be concluded that u is different from 35 minutes. To perform her statistical test, the consultant collects a random sample of shopping times at the supermarkets. She computes the mean of these times to be 39 minutes and the standard deviation of the times to be 12 minutes. Based on this information, answer the questions below. What are the null hypothesis (Ho) and the alternative hypothesis (H) that should be used for the test? Ho: H is (? H1: u is (? + ? In the context of this test, what is a Type I error? :) the hypothesis that u is + when, in fact, u is A Type I error is ? Suppese that the consultant-deeldes net te reject the null hypothesis. What sort of error might she be making?[?
