To estimate the ratio of the population variances of the monthly closing stock prices (in $)of two emerging market funds,following summary measures are obtained using the sample data for 8 months.The two samples are drawn independently from normally distributed populations.
Emerging market fund 1: = 18.65, = 0.47,and n₁ = 8
Emerging market fund 2: = 17.95, = 0.24,and n₂ = 8
Construct a 90% interval estimate of the ratio of the population variances.
