WebNov 25, 2012 · The Standard Normal distribution has a mean of 0 and a standard deviation of 1. The values inside the given table represent the areas under the standard normal curve for values between 0 and the relative z-score. The table value for Z is 1 minus the value of the cumulative normal distribution. For example, the value for 1.96 is P (Z>1.96) = .0250. WebOct 23, 2024 · Empirical rule.
