Chase and Dummer claimed that approximately 1/3 of their sample came from each district type. Let's use a goodness-of-fit test to see if there was a significant difference in the number of children from each district. Based on our results we can say: There was significantly less children from the Rural district than any other district. There was a significant difference, but we can't tell which district was significant different from other districts. There was no significant difference in the number of children from each district. There was significantly more children from the Urban district than from any other district.
