WebFeb 9, 2024 · The normal distribution is a continuous probability distribution that is symmetrical on both sides of the mean, so the right side of the center is a mirror image of the left side. The area under the normal distribution curve represents the probability and the total area under the curve sums to one. WebThe mean for the standard normal distribution is zero, and the standard deviation is one. The transformation z = x−μ σ z = x − μ σ produces the distribution Z ~ N (0, 1). The value x comes from a normal distribution …
WebThe normal distribution has the same mean as the original distribution and a variance that equals the original variance divided by the sample size. Standard deviation is the square root of variance, so the standard deviation of the sampling distribution is the standard deviation of the original distribution divided by the square root of n.
