Calculating the Percentage Above a Positive z Score
For a positive z score, we subtract the percentage between the mean and that z score from 50% (the total percentage above the mean) to get the percentage above that z score. Here, we subtract the 33.65% between the mean and the z score of 0.98 from 50%, which yields 16.35%.
