Exercise 4.62

Crown-Rump Length. In the article “The Human Vomeronasal Organ. Part II: Prenatal Development” T. Smith and K. Bhatnagar examined the controversial issue of the human vomeronasal organ, regarding its structure, function, and identity. The following table shows the age of fetuses (x), in weeks, and length of crown-rump (y), in millimeters. For part (g), predict the crown-rump length of a 19-week-old fetus.
