Find the margin of error. On September 7, 2007, 384 professional golf fans were asked “Do you think that, as a result of becoming a father, Tiger Woods’s golf game will improve, not be affected, or will get worse?” In all, 70%

said “not be affected.”

(a) What is the population for this sample survey? (Hint: See pages 8–9.)

(b) Use the quick method to find a margin of error. Then give a complete confidence statement for a conclusion about the population. (Hint: See pages 41–45.)
