Predicting height: The heights (y) and lengths of forearms (x) were measured in inches for a sample of men. The following summary statistics were obtained: :t = 10.1 sx = 0.8 y = 70.1 sy = 2.5 r=0.81
a. Compute the least-squares regression line for predicting height from forearm length.
b. Jce's forearm is I inch longer than Sam's. How much taller than Sam do you predict Joe to be?
c. Predict the height of a man whose forearm is 9.5 inches long.
