(By-Hand) Two diving judges were being trained using a new scorin they each had to judge the same six divers, and the scores each jud X consistently). Note that divers were randomly selected, and g system that might be used in future collegiate competitions. As a part of their final training assessments, ge assigned were compared for consistency (i.e., the judges were being assessed on if they judged each diver all data appears to be approximately normally distributed. Diver | 4 B | C D E _{ F 1 Judge Q 7.98 8.40 8.23 8.24 13 7.89 Judge Z 872 | 8.03 I'_ 8.55 8.65 842 | 838 a) Using the appropriate six-step testing procedure, is there sufficient evidence at the a = 0.10 significance level to conclude that the judges are not scoring consistently (i.e., that the mean difference is significantly different than zero)? b) Based upon your conclusion, either present and interpret a 90% confidence interval for the actual mean difference or explain why the test results indicate that a confidence interval is not necessary.
