3 4 of 5Question 33. We get two random samples from two normal populations. The first sample yields5.5, 8.7, 6.8, 8.9, 7.9, 8.5,and the second sample yields15.8, 14.3, 17.9,15.6, 14.7.(a) Construct a 99% confidence interval for the ratio of the two population variances if(i) you have no information on the two population means(ii) you know that the mean of the first population is 8.5(iii) you know that the first mean is 8.5 and the second mean is equal to 15.5(b) Compare, and interpret the results you have obtained. In particular, in which of these three different cases can youconclude that the two variances are equal? Carefully describe your reasoning.
