In a standard normal distribution, about 99.87% of the scores fall below a z-score of 3.00. Therefore, to find the percentage of scores that fall above a z-score of 3.00, you can subtract this value from 100%.
\[
100\% - 99.87\% = 0.13\%
\]
So, approximately **0.13%** of the scores fall above a z-score of 3.00.
\[
100\% - 99.87\% = 0.13\%
\]
So, approximately **0.13%** of the scores fall above a z-score of 3.00.
