As part of a study designed to compare hybrid and similarly equipped conventional vehicles, a group tested a variety of classes of hybrid and all-gas model cars and sport utility vehicles (SUVS). Suppose the following data show the miles-per-gallon rating obtained for tw 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. Class Туре MPG Small Car Hybrid 38 Small Car Conventional 27 Small Car Hybrid 45 Small Car Conventional 31 Midsize Car Hybrid 27 Midsize Car Conventional 23 Midsize Car Hybrid 32 Midsize Car Conventional 25 Small Suv Hybrid 26 Small SUV Conventional 22 Small SUV Hybrid 27 Small Suv Conventional 23 Midsize SUV Hybrid 23 Midsize SUV Conventional 19 Midsize SUV Hybrid 24 Midsize Suv Conventional 18 At the a = 0.05 level of significance, test for significant effects due to class, type, and interaction. Find the value of the test statistic for class. (Round your answer to two decimal places.) Find the p-value for class. (Round your answer to three decimal places.) p-value =( State your conclusion about class. O Because the p-value > a= 0.05, class is significant. O Because the p-value sa 0.05, class is significant. O Because the p-value sa = 0.05, class is not significant.
