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.

Small Car | Hybrid | 37 |
Small Car | Conventional | 28 |
Small Car | Hybrid | 44 |
Small Car | Conventional | 32 |
Midsize Car | Hybrid | 27 |
Midsize Car | Conventional | 23 |
Midsize Car | Hybrid | 32 |
Midsize Car | Conventional | 25 |
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 |
