Listed below are the weights (in lb) of cars in three different categories (from Data Set 16 in Appendix B). The Minitab display from these data is also shown. Use a 0.05 significance level to test the claim that the different car categories have the same mean weight. Do cars with more cylinders weigh more?

Interpreting a Computer Display. In Exercises 3?5, use the Minitab display on the next page, which results from the values listed in the accompanying table. The car types are foreign and domestic. The values are loads (in lb) on the left femur of crash test dummies in the same cars from Example 1 in Section 12-3.
