The claim that the variance of a normal population is σ2 = 25 is to be rejected if the variance of a random sample of size 16 exceeds 54.668 or is less than 12.102. What is the probability that this claim will be rejected even though σ2 = 25?
Answer to relevant QuestionsThe claim that the variance of a normal population is σ2 = 4 is to be rejected if the variance of a random sample of size 9 exceeds 7.7535. What is the probability that this claim will be rejected even though σ2 = 4? If 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). Use the result of Exercise 8.56 to find the probability that the range of a random sample of size n = 5 from the given uniform population will be at least 0.75.
