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 37 minutes per day. The standard deviation was 13 minutes per day. The mean listening time for a sample of 16 women was also 37 minutes, but the standard deviation of the sample was 14 minutes. At the 0.10 significance level, can we conclude that there is a difference in the variation in the listening times for men and women?
