(1 point) 1 X1, X2, X, and Xare pairwise uncorrelated random variables, each having mean 0 and variance 4 compute the covariances and correlation coefficients of each of the following. (a) X1 + X, and X2 + X2: Cov(X1 + X2, X2 + X3) = p(X + X2.X2 + X3) = (b) X1 + X, and X: + X4: Cov(X + X2, X3 + X4) = p(X; + X2, X3 + X) =
