Chapter 8, Problem 13E

To determine

To explain if you create a regression model for predicting the weight of a car in pounds from it length in feet, is the slope most likely to be $3,30,300\text{ or 3000}$ pounds.

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 $3,30,300\text{ or 3000}$ pounds. Thus, it will be $300$ pounds per foot. It is not appropriate to suggest an extra foot in length would add $3,30\text{ or 3000}$ pounds to a car’s weight.
