6. (5 points) Let X = (X1, ..., Xx) be samples from a population Pe in Theorem 1.5 on the lecture note in "Statistical Models and Sufficiency" whose the PDF can be written as fx (x, 0) = g(T (x) , 0) h(x) Show that the MLE estimate, 0 (x) must depends on x through T (x), i.e., 0 ( x ) = 0 (T (x ) )
