How many standard deviations above the mean
WebThis means P(Z > 1.282) = 0.10 approximately. So 10% of the population is above z = 1.282; when rounding to two decimal places, we get z = 1.28 We are approximately 1.28 standard deviations above the mean. A positive z score means we are above the mean z = 0, a negative score means we're below the mean.
