Question:
Suppose there are two independent normal populations with population
Transcribed Image Text:
variances o = 4.5 and o2 = 2.5, respectively. Two random samples of sizes s and s2, respectively, are drawn from the two normal populations with sample variances s, and s2, respectively. (a) What is the probability that the ratio s/s2 is greater than 4.230? (b) What is the probability that the ratio s/s22 is greater than 6.066? (c) What is the probability that the ratio s1/s2 is less than 0.5263?
