Answer to Problem 13E

  300 pounds per foot.

Explanation of Solution

It is given that if you create a regression model for predicting the weight of a car in pounds from it length in feet then is the slope most likely to be 3,30,300 or 3000 pounds. Thus, it will be 300 pounds per foot. It is not appropriate to suggest an extra foot in length would add 3,30 or 3000 pounds to a car’s weight.
