2. Suppose that x1, x2,..., In is a random sample drawn from a population whosedensity function is distributed as Exponential (VA). Suppose two possible esti-mators of A as1nÂA=and AB=2ni=11n(n + 1)2(Σ=)² f ==— e J N(a) Are the two estimators are unbiased? Then, compute the MSE of eachestimator.(b) Can you make an optimality statement about any of the proposed estima-tors Based on CRLB. What happens if n→ ∞o?
