Mariah works at a zoo. She was looking at some data showing the masses of their 5 African elephants. The mean mass of the elephants was 3, comma, 800, start text, k, g, end text, and the median mass was 3, comma, 600, start text, k, g, end text. The heaviest elephant, named Omar, was recorded as 6, comma, 000, start text, k, g, end text.
