The Average Circumferences (Distances Around) in Mm of the Humerus

The average circumferences (distances around) in mm of the humerus, femur, and tibia
of different species of mammals are displayed below. These long bones primarily
support the body mass in mammals. Each data value is the mean circumference for
the available measures for a single species. (a)Describe the differences and similarities in the distributions of these different bones.

(b) Biologists speculate that greater weights might be supported by larger bones. Based on the histograms, if the biologists' speculations are correct, which of these bones (humerus, femur, or tibia) would seem to be the least able to support a large weight? Explain, referring to specific aspects of the histograms.
