Arbitron Medla Research Incorporated 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 10 men was 35 minutes per day. The standard devlation was 10 minutes per day. The mean listening time for a sample of 13 women was also 35 minutes, but the standard devlation of the sample was 12 minutes. At the 0.10 significance level, can we conclude that there Is a difference In the varlation in the listening times for men and women? a. State the null and alternate hypotheses. and H o2#022 O Ho o?=022 and H o? =02? O Ho o?t022 and H; o? ±02? O Ho o?s02² and Hi: o?>02? b. State the decision rule. (Round your answer to 2 decimal places.) Reject Hn where F> c. Compute the value of the test statistic. (Round your answer to 2 decimal places.) The test statistic is d. Compute the p-value. (Round your answer to 4 decimal places.) p-value
