Question

How do you use z score to find p value?

Answer 1

Look up the p-value corresponding to your z-score in a standard normal table .

Example : Suppose that the z-score is `1.45`. On the lefthand side of the table look for the cell containing the first two digits of the z-score (`1.4`), then move to the column corresponding to the last digit (`.05`). The p-value for a z-score of `1.45` is `0.92647`.
