Many of the variables measured in medical testsblood pressure, triglyceride level, etc.are approximately normally distributed for the majority of the population in the United States. Thus, researchers can find the mean and standard deviation of these variables. Then using these two measures along with the z values, they can find normal intervals for healthy individuals. For example, 95% of the systolic blood pressures of healthy individuals fall within 2 standard deviations of the mean. If an individual's pressure is outside the determined normal range (either above or below), the physician will look for a possible cause and prescribe treatment if necessary. Please provide another example of the use of the Normal Distribution in real life. Be sure to read your classmates' examples and comment on at least one of them
