Questions 8-11. We will now consider factors predicting the top speed of the n=77 cars.  The relevant variables are: TOPSPEED: Top speed of the car (in miles per hour) WEIGHT: Vehicle weight (in pounds) HORSEPOWER: Maximum horsepower of the car’s engine   Summaries of two regressions predicting TOPSPEED are below:     Model 1: TOPSPEED regressed on WEIGHT Predicted TOPSPEED = 85.34 + 0.00788 WEIGHT R2 = .301   R2 (Adjusted) = .292    Residual Standard Deviation  = 8.69   Model 2: TOPSPEED regressed on WEIGHT and HORSEPOWER Predicted TOPSPEED = 96.17 – 0.00692 WEIGHT + 0.350 HORSEPOWER R2 = .951    R2 (Adjusted) = .944    Residual Standard Deviation  = 1.29
