For each scenario Listed on the left, determine whether the scenario represents an Independent Samples or Matched pairs situation by placing the appropriate Letter in the box provided. Comparing pain Levels of a group receiving a placebo to a group receiving a medicine Comparing pre-test scores before training to post-test scores Comparing the number of speeding tickets received by men to the number received by women Comparing pain Levels before and after treatment with magnetic therapy a. Matched Pairs b. Independent Samples You wish to test the following claim {Ha} at a significance level of o: = 0.05. For the context of this problem, Md 2 PostTeat 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 #1 and #2 are so that the differences are computed correctly.) Ho:#d = [I Ha3P5d 7'4 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 post-test 46.1 88.6 40.1 25 50.2 108.8 36.8 26.5 38.3 0.3 42.? 6 35.6 95.6 41.1 98.3 43.4 51 53.6 129.4 37".? 46.4 32.? -18.6 55.3 80.9 45.2 41.9 31.8 15 54.4 143.6 43.6 69.2 45 23.8 42.3 112.1 42.5 76.4 56.5 7'9 49.1 -20.4 33.5 98.1 What is the test statistic for this sample? test statistic = {Report answer accurate to 4 decimal places.)
