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.
Class | Type | MPG |
---|---|---|
Small Car | Hybrid | 36 |
Small Car | Conventional | 29 |
Small Car | Hybrid | 43 |
Small Car | Conventional | 33 |
Midsize Car | Hybrid | 28 |
Midsize Car | Conventional | 22 |
Midsize Car | Hybrid | 33 |
Midsize Car | Conventional | 24 |
Small SUV | Hybrid | 27 |
Small SUV | Conventional | 21 |
Small SUV | Hybrid | 28 |
Small SUV | Conventional | 22 |
Midsize SUV | Hybrid | 23 |
Midsize SUV | Conventional | 19 |
Midsize SUV | Hybrid | 24 |
Midsize SUV | Conventional | 18 |
At the = 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. Because the p-value = 0.05, class is significant.Because the p-value = 0.05, class is not significant. Because the p-value > = 0.05, class is significant.Because the p-value > = 0.05, class is not significant. Find the value of the test statistic for type. (Round your answer to two decimal places.)Find the p-value for type. (Round your answer to three decimal places.)p-value = State your conclusion about type.Because the p-value = 0.05, type is significant.Because the p-value > = 0.05, type is not significant. Because the p-value = 0.05, type is not significant.Because the p-value > = 0.05, type is significant.Find the value of the test statistic for interaction between class and type. (Round your answer to two decimal places.)Find the p-value for interaction between class and type. (Round your answer to three decimal places.)p-value = State your conclusion about interaction between class and type.Because the p-value > = 0.05, interaction between class and type is not significant.Because the p-value = 0.05, interaction between class and type is not significant. Because the p-value > = 0.05, interaction between class and type is significant.Because the p-value = 0.05, interaction between class and type is significant.
