An adviser is testing out a new online learning module for a placement test. They wish to test the claim that the new online learning module changed placement scores at a significance level of a = 0.05. For the context of this problem, d = μAfter Bef or e where the first data set represents the after test scores and the second data set represents before test scores. Assume the population is normally distributed. Ho: Pd=0 Ha: Hd #0 You obtain the following paired sample of 18 students that took the placement test before and after the learning module: After 65.3 40.5 47.3 79.7 60.1 47.8 28.2 53.7 82.3 62.6 40.6 47 72.4 60.4 32.3 55.2 74.1 48.5 Before 45 47.2 39.4 44.5 48.2 33.4 33.4 47.6 39.6 43.6 46.8 46.8 47.3 39.4 40 42.8 41.1 44.1 What is the critical value for this test? Round answers to 4 decimal places. critical value = +
