A variety of sources suggest that individuals asses their health, at least in part, by estimating their percentage of body fat. A widely accepted measure of body fat uses an underwater weighing technique. There are, however, more convenient methods that use only a scale and a measuring tape. An article explored regression models to predict body fat. Use the accompanying data to complete parts a and b. Loty=% Body Fat x = Age (years), x3 = Weight (lbs), x3 = Height (inches). X = Chest circumference (cm). x9 = Abdomen circumference (cm). Xe = Hip circumference (cm) and x2 = Thigh circumference (cm) Click the icon to view the data a Use best subsets stepwise regression to establish the relationship between body fat and the variables in the specified file Find the most appropriate model for the data. Note that the coefficient is for any variable that is not included in the model 9=13 (8) + ((x+x+ (3) + (x + ( x) Type Integers or decimals rounded to two decimal places as needed.)
