Weba normal distribution from its normal density curve. Students should also observe that most of the area under a normal density curve falls within three standard deviations of the mean. Therefore, the activity can serve as preparation for Unit 8, Normal Calculations, where students will learn the Empirical rule (or the 68-95-99.7% rule). WebAnswer: Is there a derivation for the 68–95–99 rule for the normal distribution? It is not exactly a derivation. The normal distribution is defined by this equation: For a standard normal or z distribution, we use mu = 0 and sigma = 1. The upper tail area for a specific value of z is found by...
