(10) For the above problem verify that the theorem of total variance (TTV) holds. The following verifications are proposed. (a) Since Var(Var(X|Y)) = o = Var(X), the TTV holds. (b) Since p*ožVar(Y) of +ož(1 – p²) = o = Var(X). Var(E(X|Y)) + E(Var(X|Y)) = the TTV holds. (c) Since Var(E(X|Y)) = Var(X) = oi, the TTV holds. (d) Since Var(E(X\Y)) = 0 and E(Var(X|Y)) = Var(X), the TTV holds. (e) None of the above The correct verification is (a) (b) (c) (d) (e) N/A (Select One)
