WebA Normal distribution is described by a Normal density curve. Any particular Normal distribution is completely specified by two numbers: its mean 𝜇 and its standard deviation 𝜎. The mean of a Normal distribution is the center of the symmetric Normal curve. The standard deviation is the distance from the center to the change- 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 …
