Among other things, the consumer group would like to do a statistical testfregarding the mean monthly mileage, u, of cars rented in the U.S. this year. The consumer group has good reason to believe that the mean monthly mileage 0 cars rented in the U.S. this year is less than last year's mean, which was 2850 miles. The group plans to do a statistical test regarding the value of u. it chooses a random sample of monthly mileages and computes the mean of the sample to be 2750 miles and the standard deviation to be 700 miles. \\ Based on this information, complete the parts below. (a) What are the null hypothesis H0 and the alternative hypothesis 1"]1 that should be used for the test? (b) Suppose that the group decides not to reject the null hypothesis. What sort of error might It be making? (Choose one) V Type II error. A Type II error would be (Choose one) v the hypothesis that p. is (Choose one) v (Choose one) Y when, in fact, 11 is (Choose one) y _ (C) Suppose the true mean monthly mileage of cars rented in the U.S. this year is 2735.
