The 68-95-99 Rule (aka, The Empirical Rule) states that all normal distributions share many common properties. In fact, all normal distributions are the same if we measure in units of o, as represented by z-scores, above and below the mean, µ. When using z-scores for measurement, the normal distribution is often also called the standard normal distribution. The heights of 64 inches and o 2.7 inches.

The 68-95-99 Rule (aka, The Empirical Rule) states that all normal distributions share many common properties. In fact, all normal distributions are the same if we measure in units of σ, as represented by z-scores, above and below the mean, μ. When using z-scores for measurement, the normal distribution is often also called the standard normal distribution. The heights of young women are approximately normal with μ = 64 inches and σ = 2.7 inches. For a woman 70 inches tall (X = 70), z = ?
