Check my work mode : This shows what is corr 5 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 10 men was 35 minutes 14.28 per day. The standard deviation was 10 minutes per day. The mean listening time for a sample of 12 women was also 35 minutes, but the standard deviation of the sample was 12 minutes. At the 0.10 significance level, can we conclude that points 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 - 02? and H1: 012 = 02 Ho: 012 = 027 and H: 012 = 02? Ho: 012 = 02 and t: 012 = 02? Ho: 012 s 022 and th: 012 2 02 b. State the decision rule. (Round your answer to 2 decimal places.) Answer is complete and correct. Reject Ho if F> 3.10 c. Compute the value of the test statistic. (Round your answer to 2 decimal places.) Answer is complete and correct. The test statistic is 1.4 40 d. Compute the p-value. (Round your answer to 4 decimal places.) X Answer is complete but not 0.2964x correct. value
