A golf pro shop is deciding whether to carry a new, more expensive line of golf balls that claim to travel further. To test the new balls, the pro shop manager asked the club’s golf pro to hit 100 of the top selling brand of balls and 100 of the new balls. The distance traveled by both the new and current balls was recorded. For this scenario, which of the following would be the proper set of hypotheses? a. H0: µD = 0 H1: µD > 0 b H0: µD = 0 H1: µD < 0 c. H0: µnew - µcurrent = 0 H1: µnew - µcurrent < 0 d. H0: µnew - µcurrent = 0 H1: µnew - µcurrent > 0 II. What is the dependent variable in this study?
