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 men was 35 minutes per day. The standard deviation of the sample of the 14 men studied was 10 minutes per day. The mean listening time for the 16 women studied was also 35 minutes, but the standard deviation of the sample was 14 minutes. At the 0.01 significance level, can we conclude that there is a difference in the variation in the listening times for men and women? a. State the decision rule. (Round the final answer to 2 decimal places.) Reject H, when F> b. Compute the value of the test statistic. (Round the final answer to 2 decimal places.) Value of the test statistic c. What is your decision regarding Ho : o = o ?
