Which of the following statements are true
1. That the expected value operator E(X) is positive means that E(X)2 0 for all X
2. The expected value operator fulfills E(aX+bY+c)=aE(X)+bE(Y)+c
3. The conditional expected value E(X|Y) is the function h(X) of X that minimize the
expected absolute error E(|h(X)-Y|)
4. If X and Y are independent variables so applies to the moment generating function for
the sum X+Y that ox+y(s) = ¢x(s)· Þy(s)
