Question
A consumer advocacy group conducts a large study on car rental practices. Among other things, the group would like to do a statistical test on the mean monthly mileage,μ, of cars rented in the US this year. The consumer advocacy group has good reason to believe that the average monthly mileage for rental cars in the US this year is higher than last year's average, which was2700miles. The group plans to perform a statistical test on the value ofu. To do this, choose a random sample of miles driven per month and calculate that the sample mean is2835miles and the standard deviation is750miles. Use this information to complete the parts below. (to) What are the null hypothesesh and the alternative hypothesish, What should be used to perform the test? h :0 0 (b) (c) h :0 1 Assume that the group decides not to reject the null hypothesis. What kind of mistake could you be making? (Choose an option) Suppose the true average monthly mileage for rental cars in the US this year is2850. Fill in the blanks to describe a type II error.
