Chapter 5.4, Problem 9E

In Exercises 107 and 108, use the following information. The relationship between the length of an adult’s femur (thigh bone) and the height of the adult can be approximated by the linear equations y = 0.514x 14.75 Female y = 0.532x 17.03 Male where y is the length of the femur in inches and x is the height of the adult in inches (see figure). Officials search a forest for a missing man who is 6 feet 2 inches tall. They find an adult male femur that is 23 inches long. Is it possible that the femur belongs to the missing man?
