Question: The Speedy Car Rental Company, with offices almost nowhere, is concern that renters are not renting their cars for long enough periods. Their two month special, “Rent this Pile of Junk” promotion only had limited success. They selected a random sample of 18 different renters at three of their locations, Peoria, Prescott, and Paducah, and found the following number of days rented during their promotion.

First write out your null and research hypotheses, next perform the correct test using the .01 level of significance, and determine if the mean number of days of car rentals was the same or different at all three locations. Remember to show your work and try to answer the question.
