WebA z score tells you about the fluctuating standard deviations from the mean state. The following p value formula from z score tells us how to find p value: P value for two-tailed test = p value from z score table * 2. P value for left0tailed test = p value from z score table. P value for right-tailed test = 1 – p value from z score table.
