Most companies that make golf balls and golf clubs use a one-armed robot named "Iron Byron" to test their balls for length and accuracy, but because of swing variations by real golfers, these test robots don't always indicate how the clubs will perform in actual use. One company in the golng industry is interested in testing its new driver to see how it compares with the best-selling driver. To do this, it has selected a group of golfers of differing abilities and ages. Its plan is to have each player use each of the two clubs and hit ve balls. It will record the average length of the drives with each club for each player. Given this description of the planned test, which of the following statements is true? 0 A. The samples in this case are called paired samples since the same players are hitting both golf clubs. 0 B. The samples are independent because each player is independent of the other players. 0 C. The test won't be meaningful if only ve balls are hit by each player with each club. 0 D. The test will be invalid unless different players are used to hit each club so that the samples will be independent
