You wish to test the following claim (HaHa) at a significance level of =0.01=0.01. For the context of this problem, d=postpred=post-pre where the first data set represents a pre-test and the second data set represents a post-test. Ho:d=0Ho:d=0 Ha:d0Ha:d0 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=348n=348 subjects. The average difference (post - pre) is d=3.9d=-3.9 with a standard deviation of the differences of sd=45.8 sd=45.8. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value =
