Verify that if Y has a beta distribution with α = v1/2 and β = v2/2 , then X = v2Y/v1(1 – Y) Has an F distribution with v1 and v2 degrees of freedom. Find the mean and the variance of the sampling distribution of Y1 for random samples of size n from the population of Exercise 8.46. Use the formula for the joint density of Y1 and Yn shown in Exercise 8.52 and the transformation technique of Section 7.4 to find an expression for the joint density of Y1 and the sample range R = Yn – Y1. What is the probability of each possible sample if (a) A random sample of size n = 4 is to be drawn from a finite population of size N = 12; (b) A random sample of size n = 5 is to be drawn from a finite population of size ...A random sample of size 100 is taken from a normal population with σ = 25. What is the probability that the mean of the sample will differ from the mean of the population by 3 or more either way?Post your question
