    X has a chi-square distribution with n degrees of freedom. Therefore E(Y) = E(X) = E(X) = n.  Proposition 3. If X has a chi-square distribution with n degrees of freedom‚ then the variance of X is X2 = E((X - X)2) = 2n. If Y/ has a chi-square distribution with n degrees of freedom‚ then the variance of Y is Y2 = 2n2. Proof. Since X ~ (n/2‚2) it follows from Proposition 3 of section 2.2 that X2 = (n/2)(22) = 2n. One has Y/ = X where X has a chi-square distribution
