Refer to Data Set 13 in Appendix B and use the pelvis decel-eration measurements for small cars, midsize cars, and large cars. Use a 0.05 significance level to test the claim that the different size categories have the same median pelvis deceleration in the standard crash test. Do the data suggest that larger cars are safer? Use the Kruskal-Wallis test with the data set from Appendix B.
