Question 513674: I need to find the lower limit and upper limit of the 99% confidence interval.
Group 1
n(down 1) = 20
sample mean (down 1) = 220.7
sample variance (up 2) (down 1) = 134.6
Group 2
n (down 2) = 17
sample mean (down 2) = 228.4
sample variance (up 2) (down 2) = 13396
Construct a 99% confidence interval for stdev(up 2)(down 1)/stdev(up 2)(down1) the ratio of the variances of these two populations.
Carry your intermediate computations to at least three decimal places. Write your final responses to at least two decimal places.
My apologies about not knowing how to write these appropriately in an electronic form and having to write them with ups and downs.

I used my TI-84 and ran a 2-SampleTInterval to get those answers.
