Section of an oil field has been divided into 48 equal sub-areas. Counting the oil wells in the 48 sub-areas gives the following frequency distribution : Number of 0 1 2 3 4 5 6 7 oil wells Number of 5 10 11 10 6 4 0 2 sub-areas Is there any evidence from these data that the oil wells are not distributed randomly throughout the section of the oil field?
