5. A researcher is interested in testing whether explaining the processes of statistics helps increase trust in computer algorithms. He wants to test for a difference at the a = 0.05 level and knows that some people may trust the algorithms less after the training, so he uses a two-tailed test. He gathers pre- post data from 35 people and finds that the average difference score is XD = 12.10 with a standard deviation of SD = 17.39. Conduct a hypothesis test to answer the research question. 6. Decide whether you would reject or fail to reject the null hypothesis in the following situations: a. E = 3.50, sD = 1.10, n = 12, a = 0.05, two-tailed test b. 95% CI = (0.20, 1.85) c. t: 2.98, t* = -2.36, one-tailed test to the left (1. 90% CI = (-1.12, 4.36)
