Nine students have been chosen to take part in a study. Each student will be taught statistics by two completely different methods and then tested on their knowledge in each class. The results of the first technique are labeled as Group 1 and the results of the second technique are labeled Group 2 as follows:

Group 1 ___ Group 2

76 83

92 91

83 72

84 93

65 75

71 87

60 75

81 79

72 74

You can assume that the average difference between these two groups is -5.00. Further, you can assume that the sample variance of the differences is 77.0. Use the appropriate procedure to test the claim that scores in these two groups are the same, using a = .10.
