Final answer:
A z-score of +1.80 corresponds approximately to the 96th percentile, meaning such an individual scores higher than about 96% of the population.
Step-by-step explanation:
A person with a z-score of +1.80 would have a percentile rank that translates to the percentage of data below that z-score. Using the Empirical Rule and z-tables, a score of +1 is approximately the 84th percentile since about 68 percent of the population falls between -1 and +1, accounting for 34 percent on each side, and +1.80 is significantly higher. Looking at a z-table or using statistical software, we find that a z-score of +1.80 corresponds to approximately the 96th percentile. Therefore, a person with a z-score of +1.80 is higher than about 96 percent of the population on the measure in question.
