You wish to test Ho:µd = 0 versus Ha: pd > 0 at a significance level of 0.10. For the context of this problem, µå = 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 ēd = 7 with a standard deviation of the differences of så = 11.6. - Round your answers to three decimal places, and round any interim calculations to four decimal places.
