1. In the table below are highway fuel consumption amounts (mi/gal) for cars categorized by size (small, midsize, large). Using a 0.05 significance level, test the claim that the three size categories have the same mean highway fuel consumption. From the sample data, does the size of a car appear to affect highway fuel consumption?

Small (mi/gal): 34 36 28 40

Midsize (mi/gal): 28 31 26 30

Large (mi/gal): 28 26 23 24
