Suppose X_1, ..., X_n is a random sample from a normal distribution with parameter μ and σ^2 . If S^2=Σ(X_i - Xbar)^2 /n , where Xbar is the sample mean, determine the distribution of nS^2 /σ^2 .
Suppose X1, X2, ..., Xn and Y1, Y2, ..., Ym are independent random samples with normal distribution with mean and variance (a1 and 9) and (a2 and 25), respectively. Using the x-bar and y-bar sample mean statistics, find the pivotal quantity for the difference in means a1-a2 !
