Question
You wish to test if the mean difference of post-test from pre-test is less than 0 (they did worse) at a significance level of 0.01. For the context of this problem, d = post-pre. You obtain pre-test and post-test samples for na = 20 subjects. The average difference (post-pre) is Ta = -6.9 with a standard deviation of the differences of sd = 38.7. Round your answers to three decimal places, and round any interim calculations to four decimal places. Fill in the hypotheses below (click the circle to the left of the correct answer): Hou_d Hau_d What is the test statistic? -0.797 0 What is the critical value for this test? Hint: Use R. 0 Using your answer from the previous question, find the p-value. 0.2176 ▼ Part 2 of 4 Part 3 of 4
