In a sample of people, the mean height was 65.2 inches and the heights range from 56 to 70 inches. The histogram for the heights is bell-shaped. The Empirical Rule states that all or almost all data fall within three standard deviations of the mean. Use this fact to find an approximation of the standard deviation. Round to one decimal place if necessary.
