You wish to test the following claim (H.) at a significance level of a = 0.002. For the context of this probiem, Hd = PostTest- PreTest where the first data set represents a pre-test and the second data set represents a post- test. (Each row represents the pre and post test scores for an individual. Be careful when you enter your data and specify what your 41 and u2 are so that the differences are computed correctly.) Ho: Hd = 0 Ha:Hd # 0 You believe the population of difference scores is normally distributed, but you do not know the standard deviation. You obtain the following sample of data: post-test 158.8 pre-test 35.5 34.1 106.5 22.5 -8.2 46.8 74.8 44.2 16.7 43.5 66.5 40.8 97.5 32.8 5.3 43.3 146.6 108.6 43.3 46.5 36.8 29.5 147.7 46 28.9 27.7 3.1 25.2 46.9 45.2 -30.4 35.2 145.1
