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 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.

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 s a = 0.05, class is not significant. 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 > a = 0.05, class is not significant. Find the value of the test statistic for type. (Round your answer to two decimal places.)
