Question

The equation used to predict the total body weight (in pounds) of a female athlete at a certain school y^= 130 + 3.25 x_1 + 2.19 x_2, where x_1 is the female athlete's height (in riches) 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 62 inches tall and has 29% body fat. The predated total body weight for a female athlete who is 62 inches tall and has 29 % body fat is pounds. (Round to the nearest tenth as needed.)

Explanation / Answer

given regression equation is
y = 130 + 3.25x1 + 2.19x2

For x1 = 62
and x2 = 29

y = 130 + 3*62 + 2.19*29 = 379.51

The predicted total body weight is 379.51 pounds
