Why is the mean of a standard normal distribution zero?

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. WebA normal distribution is a statistical phenomenon representing a symmetric bell-shaped curve. Most values are located near the mean; also, only a few appear at the left and right tails. It follows the empirical rule or the 68-95-99.7 rule. Here, the mean, median, and mode are equal; the mean and standard deviation of the function are 0 and 1 ...
