You wish to test the following claim (Ha) at a significance level of a = 0.02. For the context of thi problem, one data set represents a pre-test and the other data set represents a post-test. H.: Hd = 0 Ha: Hd + 0 You believe the population of difference scores is normally distributed, but you do not know the star deviation. You obtain pre-test and post-test samples for n = 183 subjects. The average difference 3.5 with a standard deviation of the differences of sa = 42.9. pre) is d a. What is the test statistic for this sample? test statistic = Round to 4 decimal places. b. What is the p-value for this sample? Round to 4 decimal places. p-value = c. The p-value is... less than (or equal to) a O greater than a d. This test statistic leads to a decision to... O reject the null accept the null O fail to reject the null e As such the final conclusion is that
