If S1 and S2 are the standard deviations of independent random samples of sizes n1 = 61 and n2 = 31 from normal populations with s21 = 12 and s22 = 18, find P(S21 / S22 > 1.16).
Answer to relevant QuestionsIf S21 and S22 are the variances of independent random samples of sizes n1 = 10 and n2 = 15 from normal populations with equal variances, find P(S21 / S22 < 4.03). Find the probability that in a random sample of size n = 3 from the beta population of Exercise 8.77, the largest value will be less than 0.90.
