s machines and believes that the bolts produced by machine "A" have a different variance in diameter than the variance in diameter from machine "B". A sample of 18 bolts from machine "A" has the sample variance of 0.025. A sample of 21 bolts from machine "B" has the sample variance of 0.0219. Construct the 95% confidence interval for the ratio of the population variances. Round your answers to four decimal places.
