You wish to test the following claim (HaHa) at a significance level of α=0.05. For the context of this problem, μd=μ2−μ1 where the first data set represents a pre-test and the second data set represents a post-test.      Ho:μd=0Ho:μd=0      Ha:μd>0Ha:μd>0You 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=243 subjects. The average difference (post - pre) is ¯d=2 with a standard deviation of the differences of sd=13.3.What is the critical value for this test?
