The monthly returns of two portfolios are to be compared. The monthly returns are analyzed for each of 13 months, with the months being chosen at random and independently for the two portfolios. The following statistics for monthly returns are reported for portfolio 1 and portfolio 2: Portfolio 1 Portfolio 2 X 0.12 X2=0.11 2. s30.0036 $5 = 0.0016 (The first row gives the sample means, and the second row gives the sample variances.) Assume that the monthly returns of the two portfolios are each normally distributed. Construct a 90% confidence interval for the ratio of the variances of 2 02 the monthly returns for these two portfolios. Then complete the table below. 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.) What is the lower limit of the 90% confidence interval? What is the upper limit of the 90% confidence interval? The monthly returns of two portfolios are to be compared.
