An engineer is building a regression that describes the fuel consumption of cars. The following scatterplot graphs fuel consumption (gallons per 100 miles) on horsepower; the partial regression plot on the right is from a multiple regression that includes weight as a second explanatory variable. The highlighted point is a Corvette. Why is the Corvette at the right edge of the partial residual plot rather than the car with the most horsepower?
