Standard normal table with negative values
WebbAs a result, if we want the probability that a standard normal is less than 1.45, we need to subtract the value in the table from 1: P(Z < 1.45) = 1 – P(Z >= 1.45) = 1 – .0735 =0.9265 … Webb26 mars 2024 · Definition: standard normal random variable A standard normal random variable is a normally distributed random variable with mean μ = 0 and standard deviation σ = 1. It will always be denoted by the letter Z. The density function for a standard normal random variable is shown in Figure 5.2. 1.
