This topic focuses on working with the empirical rule to determine the z-scores for given percentages of data that lie above or below certain values in a normal distribution. The problems require understanding and applying concepts from statistics and probability, particularly standard deviation and z-scores, to interpret a dataset's distribution. This involves converting a percentage of data within a normal distribution to its corresponding integer z-score.
