Normal Distribution and Standard Normal

normal distribution  The normal distribution is a continuous probability distribution that is symmetrical around its mean with most values near the central peak  This is the unshaded part of the graph from the mean to x 1 x 1 This is a normal distribution curve A value, x, is labeled on the Figure

Standard normal distribution can be used to solve problems related to probabilities of events occurring The area under the curve of the standard normal The sampling distribution of the mean becomes approximately normal regardless of the distribution of the original variable The sampling distribution of the
