Statistics and Probability

Assume that X and y are Independent random variables, and that both have the expected valve H and the variance o. Decide for each of the statements below whether it is true or false. a ) X + y have the same expected value like ZX. by X + Y have the Same variance as 2X. () - X have the expected value - 1 dj x - y have the variance O . ( ) ( xty) / 2 have the Standard deviation / 2
