For nos. 17 to 21. It is suspected that higher priced automobiles are assembled with greater care than lower priced automobiles. To investigate whether there is any basis for this idea, 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 cares were manufactured by the same company. The results of the computations are provided in the summary of ANOVA table below. 17. What is the total sum of squares of the problem. A. 7.987 B. 11.233 C. 45.876 D. 65.333
