Homework > Homework 7.2 You wish to test the following claim (H) at a significance level of a = 0.001. For the context of this problem, Md = M2 - My where the first data set represents a pre-test and the second data set represents a post-test. H:Hd = 0 Taith to 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 = 11 subjects. The average difference (post- pre) is d = 11.3 with a standard deviation of the differences of 8d = 37.5. 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 = The p-value is... O less than (or equal to) a O greater than a This test statistic leads to a decision to... O reject the null O accept the null O fail to reject the null 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 post- tartfren fcnt Ltd
