The equation used to predict the total body weight (in pounds) of a female athlete at a certain school is modifyingabove y with caret equals negative 121 plus 3.38 x 1 plus 1.48 x 2, where x1 is the female athlete's height (in inches) and x2 is the female athlete's percent body fat, measured as x2%. use the multiple regression equation to predict the total body weight for a female athlete who is 68 inches tall and has 21% body fat.
to predict the total body weight for a female athlete who is 68 inches tall and has 21% body fat, substitute the given value for each independent variable into the multiple regression equation.
substitute the values for x1 and x2 into the multiple regression equation.
