In general, E(X²) E(X)2, but E(XX) = E(X)² where X*X is the product of two (independent) random variables with idenetical distributions (i.i.d.). For our small sample, we have X₁ = 2, X₂ = 3, X3 = 3, X4 = 5. Please calculate E(X)= Please calculate E(X)² = Please calculate E(X²) = Please calculate E(X-X) =
