A pediatrician wants to determine the relation that exists between a child's height, x, and head circumference, y. Round to 4 decimals. a. Find the least-square regression line treating height, x, as the explanatory variable and the child's head circumference, y as the response variable. Round to 4 decimals. b. Use the regression equation to predict the head circumference of a child who is 25 inches tall. Round to 2 decimals. eldensy senones c. The pediatrician wants to predict a child that measures 32 inches tall, is it reasonable to use the regression equation to predict the head circumference of the child? Is so what height is predicted and if not why not
