Hi, I have completed this problem however, I am unsure if it is correct.

Citrus Rental is a popular car rental agency that has a history of having too few cars available, so that its available cars are overdriven. The mean monthly mileage over the years for Citrus cars has been about 1600 miles per month. Recently. though, Citrus purchased thousands of new cars. and the company claims that the average mileage of its cars is now less than in the past. To test this. a random sample of 20 recent mileages of Citrus cars was taken. The mean of these 20 mileages was 1466 miles per month. and the standard deviation was 250 miles per month. Assume that the population of recent monthly mileages of Citrus cars is normally distributed. At the 0.05 level of signicance, can it be concluded that the mean recent monthly mileage, p, of Citrus cars is less than 1600 miles per month? Perform a onetailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.) (a) State the null hypothesis H0 and the alternative hypothesis H1. l-i 0 p H0 : p = 1600 _ A x 5 p H1 : p
