Exhibit 2-4
In the article, "Scaling of Mammalian Long Bones: Small and Large Mammals Compared," the average circumferences (distances around) in mm of the humerus, femur, and tibia of different species of mammals were reported. These are the long bones that primarily support the body mass in mammals. Each data value is the mean circumference for the available measures for a single species.



-Refer to Exhibit 2-4.
​Biologists speculate that the different amounts of weight might be supported by different sized bones. Based on the histograms, does it seem like one of these bones has on average a greater or lesser circumferences? Explain.
