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 41 minutes per day. The standard deviation was 17 minutes per day. The mean listening time for a sample of 10 women was also 41 minutes, but the standard deviation of the sample was 9 minutes. Use a two-tailed test and at 0.10 significance level, can we conclude that there is a difference in the variation in the listening times for men and women?
