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 13 men was 40 minutes per day. The standard deviation was 11 minutes per day. The mean listening time for a sample of 12 women was also 40 minutes, but the standard deviation of the sample was 17 minutes. At the 0.02 significance level, can we conclude that there is a difference in the variation in the listening times for men and women? (Round your answer to 3 decimal places.)
