You wish to test the following claim (Ha​) at a significance level of α=0.001. d denotes the mean of the difference between pre-test and post-test scores. H0​:μd​=0Ha​:μd​=0​ 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=17 subjects. The average difference (post - pre) is d=26.5 with a standard deviation of the differences of sd​=35.3. a. What is the test statistic for this sample? test statistic = Round to 3 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) α greater than α d. This test statistic leads to a decision to... reject the null accept the null fail to reject the null e. As such, the final conclusion is that... 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 posttest 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 . 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 .
