I'm not sure what I missed here, your help is appriciated You wish to test the following claim (Ha) at a significance level of a = 0.005. For the context of this problem, µd = u2 - u1 Where the first dataset represents a pre-test and the second data set represents a post-test.H.: Ha = 0Ha: Ha + 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 = 15 subjects. The average difference (post - pre) is d = 16.6 with a standard deviation of the differences of sa = 23.8.What is the test statistic for this sample? (Report answer accurate to three decimal places.)test statistic = 2.70What is the p-value for this sample? (Report answer accurate to four decimal places.)p-value = 2.947The p-value is..less than (or equal to) agreater than aThis test statistic leads to a decision to...O reject the nullaccept the nullfail to reject the nullAs such, the final conclusion is that...O There is sufficient evidence to warrant rejection of the claim that the mean difference of post-test from pre-test is not equal to 0.There is not sufficient evidence to warrant rejection of the claim that the mean difference of post-test from pre-test is not equal to 0.The sample data support the claim that the mean difference of post-test from pre-test is not equal to 0.O There is not sufficient sample evidence to support the claim that the mean difference of post-test from pre-test is not equal to 0.
