If the mean height of the population is 68 inches and the standard deviation is 4 inches99.7 of the population will have a height within ranges?

According to the empirical rule (68-95-99.7 rule), approximately 99.7% of the population falls within three standard deviations of the mean. Given a mean height of 68 inches and a standard deviation of 4 inches, this range is calculated as follows: 68 inches ± 3(4 inches), which results in a height range of 56 inches to 80 inches. Thus, 99.7% of the population will have a height between 56 inches and 80 inches.
