You wish to test Ho: d = 0 versus H₁: μd > 0 at a significance level of 0.10. For the context of this problem, d = μ₂ μ₁ where the first data set represents a pre-test and the second data set represents a post-test. You obtain pre-test and post-test samples for na = 25 subjects. The average difference (post-pre) is d = 7 with a standard deviation of the differences of sa = 11.6. Round your answers to three decimal places, and round any interim calculations to four decimal places. What is the test statistic?
