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.
