Award: 10.00 points Suppose a sample of 49 paired differences that have been randomly selected from a normally distributed population of paired differences yields a sample mean of d = 4.0 and a sample standard deviation of So = 7.6. (a) Calculate a 95 percent confidence interval for Ma = /1 -/2. (Round your answers to 2 decimal places.) Confidence interval = (b) Test the null hypothesis Ho: Ja = 0 versus the alternative hypothesis He: No # 0 by setting a equal to . 10. .05, .01, and .001. How much evidence is there that Va differs from 0? t = Reject HO at a equal to evidence that u1 differs from p2. (c) The p-value for testing He: Ha 3 equals 0.1808. Use the p-value to test these hypotheses with a equal to . 10, .05, .01, and .001. How much evidence is there that a exceeds 3? What does this say about the size of the difference between u, and //2? (Round your p-value answer to 4 decimal places.) P = Reject Ho at a equal to evidence that u1 and u2 differ by more than 3 rev: 03_08_2022_QC_CS-297999 References Worksheet Difficulty: 2 Medium Learning Objective: 11-03 Compare two population means when the data are paired. https://ezto.mheducation.com/hm.tox?todo=c15SinglePrintView&singleQuestionNo=5.&postSubmissionView=13252719143544439&wid=1325271908... 1/1
