Webb26 mars 2024 · Figure 5.2. 1: Density Curve for a Standard Normal Random Variable. To compute probabilities for Z we will not work with its density function directly but instead read probabilities out of Figure 5.2. 2. The tables are tables of cumulative probabilities; their entries are probabilities of the form P ( Z < z). WebbThe Standard Normal Distribution Table. The standard normal distribution table provides the probability that a normally distributed random variable Z, with mean equal to 0 and variance equal to 1, is less than or equal to z. It does this for positive values of z only (i.e., z-values on the right-hand side of the mean).
