The results are shown below  Subject A B C D E F G Before 9.5 9.4 9.6 9.5 9.5 9.6 9.7 After 9.6 9.6 9.6 9.4 9.6 9.9 9.5   A) Assume data are normally distributed, use a 0.01 level of significance to test the claim that the training technique is effective in raising the gymnasts' scores. (13pts) Perform the following steps:  (2pts) Step 1: Requirements (2pts) Step 2:                 (3pts) Step 3: Test statistic (round to 3 decimals) (3pts) Step 4: Critical value (round to 3 decimals) (2pts) Step 5: Critical value Method: (1pt) Step 6: Conclusion:   B) Construct a 98% confidence interval for the mean before and after differences of the training. (6pts) Perform the following steps:              (1pt) Command:              (2pts) Information for the command:             (1pt) CI (round to 2 decimals)             (2pts) Does it appear there is a difference between the the mean before and after differences of the training?
