Transcribed Image Text:(c): Your answer is wrong.
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 ofμ. To do this, choose a random sample of miles driven per month and calculate that the sample
mean is2835miles and the standard deviation is 750miles.
Use this information to complete the parts below.
