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 = 0.432x - 10.44 (female) y = 0.449x - 12.15 (male) where y is the length of the femur in inches and x is the height of the adult in inches (see figure).   From the foot bones of an adult human male an anthropologist estimates that the person's height was 69 inches.  A few feet away from the site where the foot bones were discovered, the anthropologist discovers a male adult femur that is 19 inches long.  Is it likely that both foot bones and thigh bone came from the same person?  Explain your reasoning.
