While Dr. Sattler was performing the census of Velociraptors, she noticed that the males and females do not seem to be distributed evenly across the island. She decided to do a study on this, to see if males and females really do have different habitat preferences.On the beach, she observed 73 male Velociraptors and 66 females. In the jungle in the central portion of the island, she observed 56 male Velociraptors, and 69 females. In the alley next to the cafeteria, she observed 6 male Velociraptors, and 30 females. (She made a note to mention that people coming to and from lunch should probably avoid this alley).
