Question:
Let X1,X2, . . . , Xn be a random sample from a N(μ0, σ2 = θ) distribution, where 0 < θ < ∞and μ0 is known. Show that the likelihood ratio test of H0 : θ = θ0 versus H1 : θ ≠ θ0 can be based upon the statistic W = Σni=1(Xi − μ0)2/θ0. Determine the null distribution of W and give, explicitly, the rejection rule for a level α test.
