If we're given a particular normal distribution with some mean and standard deviation, we can use that z-score to find the actual cutoff for that percentile. In this example, we find what pulse rate represents the top 30% of all pulse rates in a population. video https://cdn.kastatic.org/ka_thumbnails_cache/ac022e1d-8317-48c0-832d-1d0bbc752318_1280_720_base.png Finding z-score for a percentile In any normal distribution, we can find the z-score that corresponds to some percentile rank.
