Suppose that the average number of miles that a car is driven in the first three years is 41,500. To determine whether leased cars are driven more than “average”, 25 leased cars were sampled and the average Number of miles on the leased cars was 43,780 with a standard deviation of 10,520. To determine whether the average number of miles on leased cars is statistically significantly greater than the number of miles on other cars, what is the null and alternative hypothesis?

Suppose that the average number of miles that a car is driven in the first three years is 41,500. To determine whether leased cars are driven more than "average", 25 leased cars were sampled and the average number of miles on the leased cars was 43,780 with a standard deviation of 10,520. To determine whether the average number of miles on leased cars is statistically significantly greater than the number of miles on other cars, what is the null and altemative hypothesis?
