Let X₁, , Xn be a random sample from a large population following a uniform distribution over [0, K]. We do not know K and we want to estimate it. Define - 1/(X₁) ·(X₁ +... + Xn), n (a) What is the expected value of X¡ (for any i = 1,...,n)? (State it as a function of K) (b) Find E(X). (c) Is X an unbiased estimator of K? =
