, xn be a sample with joint pdf (or pmf) f(Xn10), θ 3. Let Xi, Θ C R. Suppose that {f(x,10) : θ E Θ} has monotone likelihood ratio (MLR) in T(Xn). Consider test function if T(%) > c Xn if T(%) < c, where γ E [0, 1) and c 〉 0 are constants. Prove that the power function of φ(Xn) is non-decreasing in θ
