In an article it was claimed that the average supermarket trip takes 22 minutes. Suppose that, in an effort to test this claim, a sample of 50 shoppers at a local supermarket were studied. The mean shopping time for the sample of 50 shoppers was 25.36 minutes with a standard deviation of 7.24 minutes. Using the 0.10 level of significance, is there evidence that the mean shopping time at the local supermarket is different from the claimed value of 22 minutes? Find sample standard deviation, sample mean, Ho, Ha, decision rule, tc, decision, and conclusion.
