A jar manufacturer is very concerned about the consistency of the diameters of jars produced by his machines and believes that the jars produced by machine $"$A$"$ have a different variance in diameter than the variance in diameter from machine $"$B$".$ A sample of $18$

jars from machine $"$A$"$ has the sample variance of $0\mathrm{.}0494$

$.$ A sample of $22$

jars from machine $"$B$"$ has the sample variance of $0\mathrm{.}0424$

$.$ Construct the $95\%$

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