WebSuppose I have only two data describing a normal distribution: the mean $\mu$ and variance $\sigma^2$. I want to use a computer to randomly sample from this distribution such that I respect these two statistics. It's pretty obvious that I can handle the mean by simply normalizing around 0: just add $\mu$ to each sample before outputting the sample.
