WebLet us assume we want to compute the x x score so that the cumulative normal probability distribution is 0.89. First, the z-score associated to a cumulative probability of 0.89 is z_c = \Phi^ {-1} (0.89) = 1.227 zc = Φ−1(0.89) = 1.227 This value of z_c = 1.227 zc = 1.227 can be found with Excel, or with a normal distribution table. In statistics, a standard normal table, also called the unit normal table or Z table, is a mathematical table for the values of Φ, the cumulative distribution function of the normal distribution.
