To determine To formulate: a. The null hypothesis and the alternative hypothesis, and b. Discuss whether the sample provides evidence for rejecting or not rejecting the null hypothesis Explanation Given: a. The owner of a car rental company is making claims that the average annual mileage for all the cars in his fleet is more than the average annual mileage for all cars in the United States, 11 , 725 miles . b. The mean annual mileage for a sample size of 225 cars from the fleet is 12,000 miles . Also the probability of selecting a random sample with a mean annual mileage of 12,000 miles or more is 0 .01 . Calculation: a. The owner of a car rental company is making claims that the average annual mileage for all the cars in his fleet is more than the average annual mileage for all cars in the United States, 11 , 725 miles . The null hypothesis in this case would be that the average annual mileage of the cars in the fleet is equal to 11 , 725 miles The alternate hypothesis would be that the average annual mileage of the cars in the fleet is greater than 11 , 725 miles b. The mean annual mileage for a sample size of 225 cars from the fleet is 12,000 miles ...
