- QUESTION: Let X have the density f(x) = 2x if 0 < x <1 and f(x) = 0 otherwise. Show that X has the mean 2/3 and the variance 1/18. Find the mean and the variance of the random variable Y = -2x + 3.
The Standard Normal distribution is just a normal distribution with u = 0 and o? = 1. It turns out that if we standardize a Normal random variable X with parameters u, o in the following way X- u = 2 The expected value of the transformation is 0 and the variance is 1. So if Z=0.2, when u = 3 and o = t 0.2, the normal random variable X has value
