Consider (Test A - Test B) Use a 0.05 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? O A. Two Sample z B. Matched Pairs o O 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 0b Yes 2. Construct a 95% confidence interval for the mean of the differences. Again, use (Test A - Test B).
