The difference of two normal random variables is also normal, so we can now find the probability that the woman is taller using the z-score for a difference of 0. (8) The moment generating function corresponding to the normal probability density function N(x;, 2) is the function Mx(t) = exp{t + 2t2/2}. Since a chi-squared distribution is a special case of a gamma distribution with scale equal to 2, it is easy to see that if you multiply the random variable with a constant it no longer follows the chi-squared distribution.
