Suppose we have a scatter diagram for the heights of 3,000 pairs of fathers and sons. The summary statistics are: average height of fathers = 70 inches SD = 8 inches average height of sons = 72 inches SD = 4 inches, r = 0.7 Find linear regression line for predicting height of the father(y variable) from the height of their sons( variable). Use it to predict the height of a father whose son's height is 85 inches
