5. (2 points) Let S denote the sample variance for a random sample of size 10 from Pop-
ulation I and let S denote the sample variance for a random sample of size 8 from
Population II. The variance of Population I is assumed to be three times the variance of
Population II. Find two numbers a and b such that P(a ≤ si/s≤ b) = 0.90 assuming
S to be independent of S.
