(5.55) The Masters is one of the four major golf tournaments. Only the 60 golfers with the lowest two-round total advance to the final two rounds (unless several people are tied for 60th place, in which case all those tied for 60th place advance). Suppose that for a certain year the least-squares line for predicting second-round scores from first-round scores has equation

y=51.4+0.318xy^=51.4+0.318x

(a) Find the predicted (0.001) second-round scores for a player who shot 80 in the first round

(b) Find the predicted (0.001) second-round scores for a player who shot 70 in the first round
