Chapter 13.1, Problem 1PB
Predicting weight For a study of female college athletes, the prediction equation relating y = total body weight (in pounds) to x1 = height (in inches) and x2 = percent body fat is
- a. Find the predicted total body weight for a female athlete at the
mean values of 66 and 18 for x1 and x2. - b. An athlete with x1 = 66 and x2 = 18 has actual weight y = 115 pounds. Find the residual and interpret it.
