In Exercises 1-4, use the following listed chest deceleration measurements (in g, where g is the force of gravity) from samples of small, midsize, and large cars. (These values are from Data Set 13 in Appendix B.) Also shown (on the next page) are the SPSS results for analysis of variance. Assume that we plan to use a 0.05 significance level to test the claim that the different size categories have the same mean chest deceleration in the standard crash test.
Chest Deceleration Measurements (g) from a Standard Crash Test
Small | 44 | 39 | 37 | 54 | 39 | 44 | 42 |
Midsize | 36 | 53 | 43 | 42 | 52 | 49 | 41 |
Large | 32 | 45 | 41 | 38 | 37 | 38 | 33 |
