2. Let X₁,..., Xn (n > 2) be a random sample from the Binomial (2,0) distribution, with probability mass function P(X₁ = k) = (2) 0¹ (1 - 0)²-k for k= 0, 1, 2. (a) Argue that Xi is a complete sufficient statistic for 0. (b) We are interested in estimating 04. By improving the estimator I(X₁ = 2, X₂ = 2) using the Rao-Blackwell theorem, find the best unbiased estimator of 04.

2. Let X₁,..., Xn (n > 2) be a random sample from the Binomial (2, 0) distribution, with probability mass function P(X; = k) = (²) ø^(1 1 - 0)²-k for k= 0, 1, 2. (a) Argue that ΣX, is a complete sufficient statistic for 0. (b) We are interested in estimating 04. By improving the estimator I(X₁ = 2, X₂ = 2) using the Rao-Blackwell theorem, find the best unbiased estimator of 04.
