Question

The equation used to predict the total body weight (in pounds) of a female athlete at a certain school is y = -127+3.07x_1+1.88x_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 66 inches tall and has 29% body fat. The predicted total body weight for a female athlete who is 66 inches tall and has 29% body fat is pounds. (Round to the nearest tenth as needed.)

Explanation / Answer

from above given regression equation

predicted weight =-127+3.07*66+1.88*29% =76.1652
