Arbitron Media Research Inc. conducted a study of the IPod listening habits of men and women. One facet of the study Involved the mean listening time. It was discovered that the mean listening time for a sample of 11 men was 30 minutes per day. The standard deviation was 13 minutes per day. The mean listening time for a sample of 18 women was also 30 minutes, but the standard deviation of the sample was 13 minutes. At the 0.02 significance level, can we conclude that there is a difference in the variation in the listening times for men and women? Required: a. State the null and alternate hypotheses. HO: 0,2=022 and Hp: 0,2 +022 Ho: 02-022 and Hy: 02-022 Ho: 0,2 +022 and H: 0120022 HO: 02302 and Hp: 012022 b. State the decision rule. (Round your answer to 2 decimal places.) Reject Hoiff 3.50 c. Compute the value of the test statistic. (Round your answer to 2 decimal places.) The test statistic is 1.00 d. Compute the p-value. (Round your answer to 4 decimal places.) p-value
