2. Let Xn ~ NG, Intuitivel y, Xn will concentrate at as n -o. In this question, we will justify this intuition using the convergence concepts we learned (a) Show that Xn, 4> 1/2. (Recall for a random variable X which takes value 1/2 with all probability, its c.d.f. Fo is given by Fo(t) 0 for all t< 1/2, Fo(t)1 for all t 2 1/2. You need then to show the c.d.f. of Xn, say F(t), converges to Fo(t) at...
