Here are advertised horsepower ratings and expected gas mileage for several 2007 vehicles as reported by Kelly Blue Hook
Answers:
Part A: The linear function for this data is f(x)= -0.0838x + 46.868.
The predicted gas mileage for the Volkswagen Beetle is
30; 34.3; 59.4
and the residual is
-4.3; 4.3; 29.4; -29.4
Part B: If we add the McLaren F1 to our data set, it has a horsepower of
627, the residual for this car would be:
17.7 as the actual gas mileage recorded is 12 mpg.
-5.7 as the actual gas mileage recorded is 12 mpg.
12 as the actual gas mileage recorded is 12 mpg.
