You wish to test the following claim (Ho) at a significance level of a = 0.01. For the context of this problem, µd = µ2 – µi where the first data set represents a pre-test and the second data set represents a post-test. Ha: µd + 0 0 = Prl :°H 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 = 14 subjects. The average difference (post - pre) is d = 30.5 with a standard deviation of the differences of sa = 47.5. What is the critical value for this test? (Report answer accurate to two decimal places.) critical value = ± What is the test statistic for this sample?
