**Question description**

Please include the formula

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 10
men studied was 10 minutes per day. The mean listening time for the 12 women studied was also 35 minutes, but the standard deviation of the
sample was 12 minutes. At the .10 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.)**
