The earnings of a PGA Tour golfer are determined by performance in tournaments. A study analyzed tour data to determine the financial return for certain skills of professional golfers. The sample consisted of 393 golfers competing in one or both of the 2002 and 2008 seasons. The most significant factors that contribute to earnings were the percent of attempts a player was able to hit the green in regulation (GIR), the number of times that a golfer made par or better after hitting a bunker divided by the number of bunkers hit (SS), the average of putts after reaching the green (AvePutt), and the number of PGA events entered (Events). The resulting coefficients from multiple regression to predict 2008 earnings are:

a. State the regression formula for a PGA Tour golfer€™s earnings for 2008.
b. Explain how to interpret the coefficients for AvePutt and Events.
c. Find the predicted total score for a golfer who had a GIR score of 60, SS score of 50, AvePutt is 1.5, for 20 Events.
