Brown Tree Snakes Are an Invasive Species Causing Huge Environmental

Brown tree snakes are an invasive species causing huge environmental and financial damage in Guam. In June 2000, researchers captured 504 brown tree snakes on Guam's Andersen Air Force Base. On average, the snakes weighed 121 g, and their weights ranged from 23 to 663 g at capture. From this information, what can we conclude about the shape of the distribution of brown tree snake masses?

A) It must be roughly symmetric.
B) It must be left-skewed, have a low outlier, or both.
C) It must be right-skewed, have a high outlier, or both.
D) It must be multimodal (multiple-peaked) .
