0 Question 18 v You wish to test the following claim [H5] at a significance level of or = 0.001. For the context of this problem, Jud = Poszest PreTest where the first data set represents a pretest 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 p11 and m are so that the differences are computed correctly.) Holpd = [l Hutpd 75 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: pre-test past-test 518 145.2 56.4 53.6 41.6 83.9 36.?r 56.1 42.4 41.9 75.8 101.? 54.3 4?.8 53.2 9?.3\" 26.3 9.8 60.4 84.4 51.6 61.5 51.3 89.5 44.9 113 33.3 86.1 38.4 62.4 59.3 134 32.5 2?.3 What is the test statistic for this sample? test statistic = I I (Report answer accurate to 4 decimal places.) What is the p-value for this sample? p-value = I I [Report answer accurate to 4 decimal places.) The p-value is... '22} less than [or equal to] a {:21- greater than a This test statistic leads to a decision to... '22} reject the null -SI_IS- accept the null -SI_.1' fail to reject the null As such. the final conclusion is that... {:21- There is sufficient evidence to warrant rejection of the claim that the mean difference of post-test from pre-test is not equal to 0. Ci- There is not sufficient evidence to warrant rejection of the claim that the mean difference of postv test from pre-test is not equal to O. \":3 The sample data support the claim that the mean difference of post-test from prevtest is not equal to 0. {:21- There is not sufficient sample evidence to support the claim that the mean difference of post-test from pre-test is not equal to 0
