Finding critical value on ti 84.

A z-score tells us how many standard deviations away a given value is from the mean. The z-score of a given value is calculated as: z-score = (x – μ) / σ. where: x: individual value. μ: population mean. σ: population standard deviation. This tutorial explains how to calculate z-scores on a TI-84 calculator.
