You wish to test the following claim (H) at a significance level of a = 0.02. For the context of this problem, d = 2-₁ where the first data set represents a pre-test and the second data set represents a post-test. Ho:|d = 0 Ha: Md <0 You believe the population of difference scores is normally distributed, but you do not know the standard deviation. You obtain pre-test and post-test samples for n = 46 subjects. The average difference (post-pre) is d = - 11 with a standard deviation of the differences of sa = 26.6. What is the test statistic for this sample? (Report answer accurate to three decimal places)
