Two samples are taken from different populations, one with sample size n1=5 and one with sample size n2=11. The mean of the first sample is Xˉ1=37.9 and the mean of the second sample is Xˉ2=406.3, with variances s12=64.2 and s22=135.1, repectively. Can we conclude that the variances of the two populations differ (use α=.05 )?
