Using tho Kruskal-Wallis Test. In Exercises 5-8, use the Kruskal-Wallis test.
8. Highway Fuel Consumption Listed below are highway fuel consumption amounts (mi/gal) for cars categorized by the sizes of small, midsize, and large (from Data Set 20 “Car Measurements” in Appendix B). Using a 0.05 significance level, test the claim that the three size categories have the same median highway fuel consumption. Does the size of a car appear to affect highway fuel consumption?
| Small | 28 | 26 | 23 | 24 | 26 | 24 | 25 |
| Midsize | 28 | 31 | 26 | 30 | 28 | 29 | 31 |
| Large | 34 | 36 | 28 | 40 | 33 | 35 | 26 |
