"WebbSince the z-score is the number of standard deviations above the mean, z = (x - mu)/sigma. Solving for the data value, x, gives the formula x = z*sigma + mu. So the data value equals the z-score times the standard deviation, plus the mean. Have a blessed, wonderful day! " - Standard normal table for z scores
