A coach uses a new technique to train gymnasts. Seven gymnasts were randomly selected and their competition scores were recorded before and after the training. The data are below. Using a .01 level of significance, test the claim that the training technique appears to be effective in raising the gymnasts' scores. Use JMP to derive your answer. Before: 9.7 9.6 9.6 9.6 9.6 9.7 9.4 After: 9.8 9.8 9.6 9.5 9.7 10.0 9.2 Based on the output, the final decision should be to: а. Reject the null hypothesis because there is less than a 1% chance of committing a Type I error. b. Fail to reject the null hypothesis because there is less than a 1% chance of committing a Type l error. Fail to reject the null hypothesis because there is greater than a 1% chance of committing a Type I C. error. d. Reject the null hypothesis because there is greater than a 1% chance of committing a Type I error.
