The mean listening time for asample of 10 women was also 34 minutes, but the standard deviationof the sample was 7 minutes. Use a two-tailed test and at 0.02significance level, can we conclude that there is a difference inthe variation in the listening times for men and women? (Round youranswer to 3 decimal places.) The test statistic is . Decision:H0:σ21=σ22.
