Horsepower again Exercise 16 describes a regression model that uses a car’s horsepower to estimate its fuel economy. In this context, what does it mean to say that a certain car has a positive residual?

Exercise 16

Horsepower The relationship between the fuel economy (mpg) and horsepower for 15 models of cars produces the regression model mpg = 43.45 - 0.070 HP. If the car you are thinking of buying has a 200-horsepower engine, what does this model suggest your gas mileage would be?
