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, I, spent by customers at the supermarkets has been reported to be 35 minutes, but executives have good reason to believe that I is greater than 35 minutes. The executives hire a statistical consultant and ask her to perform a statistical test. 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 10 minutes. Based on this information, complete the parts below. (0) What are the null hypothesis /, and the alternative hypothesis /7, that should be used for the test? H :I H, :1 020 0=0 0#0 (b) Suppose that the consultant decides not to reject the null hypothesis. What sort of error might she be making? X 5 ? (Choose one) (c) Fill in the blanks to describe the Type II error that could occur if the true mean shopping time spent by customers at the supermarkets is 42 minutes. A Type II error would be (Choose one) the hypothesis that u is (Choose one) (Choose one) when, in fact, His (Choose one)
