Question
Random samples are drawn independently from two normally distributed populations, and the following statistics are obtained.
Group 1 2₁ =
13x₁=231.8=136.9

(The first row gives the sample sizes, the second row gives the sample means, and the third row gives the sample variances.)
Construct a 90% confidence interval for the ratio of the variances of these two populations. Then find the lower limit and upper limit of the 90%
