In a large state, 20% of all family households have no children, 30% of all family households have one child, and 50% of all family households have more than one child. A city councilman in a large city in the state wondered if the distribution of households in his city is different than the
distribution in the state. The councilman took a random sample of 125 family households and asked how many children each family had. The
table below displays the results of the survey.
