questionThe U.S. Department of Energy's Fuel Economy Guide provides fuel efficiency data for cars and trucks (Fuel Economy website, September 8, 2012). A portion of the data for 149 compact, midsize, and large cars is shown in the mentioned table. The data set contains the following variables:
Size: Compact, Midsize, and Large
Displacement: Engine size in liters
Cylinders: Number of cylinders in the engine
Drive: All wheel (A), front wheel (F), and rear wheel (R)
Fuel Type: Premium (P) or regular (R) fuel
City MPG: Fuel efficiency rating for city driving in terms of miles per gallon
Hwy MPG: Fuel efficiency rating for highway driving in terms of miles per gallon
