WebA normal distribution is a statistical phenomenon representing a symmetric bell-shaped curve. Most values are located near the mean; also, only a few appear at the left and right tails. It follows the empirical rule or … WebAboutTranscript. The empirical rule (also called the "68-95-99.7 rule") is a guideline for how data is distributed in a normal distribution. The rule states that (approximately): - 68% of the data points will fall within one standard deviation of the mean. - 95% of the data points will fall within two standard deviations of the mean. - 99.7% of ...

WebIn any normal distribution, we can find the z-score that corresponds to some percentile rank. 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 ... http://openbooks.library.umass.edu/p132-lab-manual/chapter/the-normal-distribution-and-standard-deviation/
