A can manufacturer is very concerned about the consistency of the diameters of cans produced by his machines and believes that the cans produced by machine "A" have a different variance in diameter than the variance in diameter from machine "B". A sample of

20 cans from machine "A" has the sample variance of

0.0369. A sample of

24 cans from machine "B" has the sample variance of

0.0359. Construct the

99% confidence interval for the ratio of the population variances. Round your answers to four decimal places.
