Normal approximation to the binomial Example #1, Normal approximation to the binomial Example #2, Find the number of occurrences or trials (, Check if the number of trials is sufficiently high (. The idea of using z-score is to asses how far a score is from the mean, relative to the size of the standard deviation. Tables, Other P (z<2.36) P (z>0.67) P (0 z) ), whereas a two-tailed p-value / percentile refers to the cumulative probability contained in the union of the areas to the right of -Z and to the left of Z ( P(X < -|z| X > |z|) ).
