Chapter 13.5, Problem 32E
As part of a study designed to compare hybrid and similarly equipped conventional vehicles. Consumer Reports tested a variety of classes of hybrid and all-gas model cars and sport utility vehicles (SUVs). The following data show the miles-per-gallon rating Consumer Reports obtained for two hybrid small cars, two hybrid midsize cars, two hybrid small SUVs, and two hybrid midsize SUVs: also shown are the miles per gallon obtained for eight similarly equipped conventional models.
At the α = .05 level of significance, test for significant effects due to class, type, and interaction.
