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 13 men was 30 minutes per day. The standard deviation was 13 minutes per day. The mean listening time for a sample of 11 women was also 30 minutes, but the standard deviation the sample was 14 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: 012-022 and H₁: 0₁²02² Ho: 02-0₂2 and H₁ 01²-022 Ho: 0₁2022 and Hy: 0₁² 0₂² Ho: 012 5022 and H 0₁²>02² b. State the decision rule. (Round your answer to 2 decimal places.) Reject H₂ F> c. Compute the value of the test statistic. (Round your answer to 2 decimal places.) The test statistic is 43
