A pediatrician wants to determine the relation that exists between a child's height, x, and head circumference, y. She randomly selects 11 children from her practice, measures their heights and head circumferences and obtains the accompanying data. (a) Find the least-squares regression line treating height as the explanatory variable and head circumference as the response variable. The least-squares regression line is (Round to four decimal places as needed.) Height, x (inches) Head circumference, y (inches) 27.75 17.7 24.5 17.1 25.5...
a pediatrician wants to determine the relation that exists between a child's height,x, and head circumference, y,. She randomly selects 11 children from her practice, measures their heights and head circumferences, and obtains the least square regression equation of y= 0.0142x+13.589. interpret the y- intercept, if appropriate. a) for a head circumference of 0 inches, the height is predicted to be 13.589 inches b) for every inch increases in head circumference, the height increases by 0.142 inches, on average c)...
