Random samples are drawn independently from two normally distributed populations, and the following statistics are obtained. Group 1 Group 2 n = 15 12 = 24 x = 298.1 X, =239 Si = 146.4 $2- 269 (The first row gives the sample sizes, the second row gives the sample means, and the third row gives the sample variances.) Construct a 99% confidence interval for the ratio of the variances of these two populations. Then find the lower limit and upper limit of the 99% confidence interval. Carry your intermediate computations to at least three decimal places. Write your final responses to at least two decimal places. (If necessary, consult a list of formulas.) Lower limit: X ? Upper limit
