Petroleum pollution in oceans stimulates the growth of certain bacteria. An assessament of this growth has been made by counting the bacteria in each of 6 randomly chosen spedimens of ocean water (of a fixed size). The 6 counts obtained were as follows. 40, 65, 67, 61, 57, 46 Send data to calculator Find the standard deviation of this sample of numbers. Round your answer to two decimal places.
