Let X1,X2,...,Xn and Y1,Y2,...,Ym be independent random samples drawn from normal distributions with means μX and μY , respectively, and with the same 2 known variance σ . Use the generalized likelihood ratio criterion to derive a test procedure for choosing between H0:μX =μY and H1:μX not equal to μY.

Suppose that X1, X2, , Xm and Y1, Y2, , Yn are independent random samples, with the variables Xi normally distributed with mean μ1 and variance σ12 and the variables Yi normally distributed with mean μ2 and variance σ22. The difference between the sample means, X − Y, is then a linear combination of m + n normally distributed random variables and, by this theorem, is itself normally distributed. (a) Find E(X − Y). (b) Find V(X − Y). (c)...
