Here are the golf scores of 12 members of a college women's golf team in two rounds of tournament play. (A golf score is the number of strokes required to complete the course, so that low scores are better.) 1 2 3 4 5 6 7 8 9 10 11 12 89 90 87 95 86 81 102 105 83 88 91 79 94 85 89 89 81 76 107 89 87 91 88 80 Player Round 1 Round 2 (a) Make a scatterplot of the data, taking the first round score as the explanatory variable. (Because both variables have the same scale, you should use the same scale on both axes of your plot, as in Figure 5-4.) (b) Is there an association between the two scores? If so, is it positive or negative? Explain why you would expect scores in two rounds of a tournament to have an association like that you observed. (c) The plot shows one outlier. Circle it. The outlier may occur because a good golfer had an unusually bad round or because a weaker golfer had an unusually good round. Can you tell from the data given whether the outlier is from a good player or a poor player? Explain your answer.
