Given that X1, X2, ... Xn are i.i.d. random variables.

Suppose X1, X2, ... Xn are i.i.d. random variables. Select all the statements that are TRUE about the random variables X1, X2, ...

Xn. O Pr(X1 < 5|X2 < 5 and X3 < 5 and ... Xn < 5) > Pr(X1 < 5) (In other words, the probability that X1 is smaller than 5, conditional on all the other random variables being smaller than 5, is greater than the unconditional probability of X1 being smaller than 5) Var(X1+X2+X3+ ...+Xn) = Var(X1) + Var(X2) + Var(X3) + ... + Var(Xn)
