Question

The equation used to predict the total body weight (in pounds) of a female athlete at a certain school is y = - 116 + 3.76x_1 + 102x_2, where x_1 is the female athlete's height (in inches) and x_2 is the female athlete's percent body fat, measured as x_2%. Use the multiple regression equation to predict the total body weight for a female athlete who is 60 inches tall and has 18% body fat. The predicted total body v/eight for a female athlete who is 60 inches tall and has 18% body fat is pounds. (Round to the nearest tenth as needed.)

Explanation / Answer

Ans:

Perdicted value of y is given by:

y=-116+3.76x1+1.02x2

when x1=60 inches

x2=18%

y=-116+3.76*60+1.02*18

y=-116+225.6+18.36

y=127.96 pounds
