If we want to be 95% confident, we need to build a confidence interval that extends about 2 standard errors above and below our estimate. More precisely, it's actually 1.96 standard errors. This is called a critical value (z*). We can calculate a critical value z* for any given confidence level using normal distribution calculations.

WebThe formula for determining the Z-score is: z= (x-m)/s Where x is the observation, m is the mean and s is standard deviation. A standard observation is used to determine how many standard deviations the original observation falls from the mean.
