peterson automotive is a local dealership selling honda automobiles. it recently stated in an advertisement that honda owners average at least 90,000 miles before trading in or selling their honda. an independent agency is skeptical of the claim and they want to test it. they select a random sample of 80 honda owners who had either traded or sold their honda and determined the number of miles on the car when the owner parted with it. if the agency wants to substantiate from the data that that the mean mileage in the population is less than 90,000, what hypotheses should they use?
