Ten randomly selected people took an IQ test A, and next day they took a very similar IQ test B. Their scores are shown in the table below. Person A B C DEF GHI Test A 96 109 102 108 8796 125 71 119 89 Test B 98 112 101 112 88 97 125 74 117 89 1. Consider (Test A - Test B). Use a v.v. significance level to test the claim that people do better on the second test than they do on the first. (Note: You may wish to use software.) (a) What test method should be used? A. Matched Pairs O B. Two Sample z . C. Two Sample t (b) The test statistic is (c) The critical value is (d) Is there sufficient evidence to support the claim that people do better on the second test? O A. No O B. Yes2. Construct a 99% confidence interval for the mean of the differences. Again, use (Test A - Test B).
