TABLE 14-15
An automotive engineer would like to be able to predict automobile mileages. She believes that the two most important characteristics that affect mileage are horsepower and the number of cylinders (4 or 6) of a car. She believes that the appropriate model is
Y = 40 - 0.05X 1 + 20X 2 - 0.1X 1 X 2
where X 1 = horsepower
X 2 = 1 if 4 cylinders, 0 if 6 cylinders
Y = mileage.
-Referring to Table 14-15, the predicted mileage for a 300 horsepower, 6-cylinder car is______
