A cоаch uses а new technique tо trаin gymnasts. 7 gymnasts were randоmly selected and their competition scores were recorded before and after the training. 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) Use a 0.01 level of significance, test the claim that the training technique is effective in raising the gymnasts' scores. (2pts) Step 1: Requirements (2pts) Step 2: H 0 H 1 (3pts) Step 3: Test statistic: (2pts) Step 4: Critical value (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. (1pt) Command: (2pts) Information for the command: (1pt) CI: (2pts) Does it appear there is a difference between the the mean before and after differences of the training? Explain C) (1pt) Are the hypothesis test and the confidence interval giving the same result?
