Question 3 (20 marks) a). Let X, be iid, E(X) = μ and Var(X) = o². Set X = Xi/n. Show that i=1 n ¹Σ(X₁-X) ² ² 0²² n i=1 (10 marks) b). Suppose X, x ≥ 1 are independent random variables and suppose that X, has a gamma density fk (x) fk (x) = -,x>0, yk>0 Γ(γκ) Give necessary and sufficient conditions for E-1 X to converge almost surely.
