Suppose a doctor measures the height, x, and head circumference, y, of 8 children and obtains the data below. The correlation coefficient is 0.909 and the least squares regression line is y= 0.184x + 12.372. Complete parts a and b below. Height, x Head Circumference, y (a) Compute the coefficient of determination, R².
