Data From Exercise R2.8
Marine biologists warn that the growing number of powerboats registered in Florida threatens the existence of manatees. The data in the table come from the Florida Fish and Wildlife Conservation Commission (myfwc.com/research/manatee/) and the U.S. Coast Guard Office of Auxiliary and Boating Safety (www.uscgboating .org/library/accident-statistics/Recreational-Boating-Statistics- 2015.pdf).
