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 ... WebAnswer. In order to find the unknown mean 𝜇 and standard deviation 𝜎, we code 𝑋 by the change of variables 𝑋 ↦ 𝑍 = 𝑋 − 𝜇 𝜎.
