It is suspected that the higher-priced automobiles are assembled with greater care than lower- priced automobiles. To investigate whether there is any basis for this feeling, a large luxury model A, a medium-size sedan B, and a subcompact hatchback C were compared for defects when they arrived at the dealer's showroom. All cars were manufactured by the same company. The number of defects for several of the three models are recorded below. Number of Automobile Defects Model A В C 4 5 8 7 1 6 8 6 9. 5 4 Total 23 21 36 80 Test the hypothesis at the 0.05 level of significance that the average number of defects is the same for the three models.
