As part of a study designed to compare hybrid and similarly equipped conventional vehicles, a variety of classes of hybrid and all-gas model cars and sport utility vehicles (SUVS) were tested. The data showing the miles-per- gallon rating study obtained for two hybrid small cars, two hybrid midsize cars, two hybrid small SUVS, two hybrid midsize SUVS, and eight similarly equipped conventional models are contained in the Excel Online file below. Construct a spreadsheet to answer the following questions. Open spreadsheet a. At the a = .05 level of significance, test for significant effects due to class, type, and interaction. Sum of Squares (to 2 decimals) Mean Square (to 2 decimals) Source Degrees of Freedom (to 2 decimals) of Variation Class Туре Interaction Error Total b. The p-value for the class of vehicle is What is your conclusion with respect to the dass of vehicle? There is sufficient O evidence to conclude that the fuel efficiency not the same for the four classes of vehicle. C. The p-value for the type of vehide is What is your conclusion with respect to the type of vehicle? There is sufficient O evidence to conclude that the fuel efficiency is not the same for the two types of vehicle. d. The p-value for the interaction between class and type of vehicle is What is your conclusion with respect to the interaction between dass and type of vehicle? The interaction between type and dass of vehicle is not O statistically significant.
