Person A B C D E F G H I J Test Score 93 73 96 72 91 78 84 83 88 67 Use a 0.05 significance level to test the claim that people do better with the new edition. Assume the standard deviation is 10.2. (a) What kind of test should be used? OA. Two-Tailed OB. One-Tailed O C. It does not matter. (b) The test statistic is (rounded to 2 decimals). (c) The P-value is (d) is there sufficient evidence to support the claim that people do better than 75 on this exam? OA. No OB.
