H.: Ha = 0 Ha:Ha > 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 = 25 subjects. The average difference (post - pre) is d = 8.8 with a standard deviation of the differences of sa = 27.6.
