For a school project, Max must design a survey. For his survey he plans to randomly select families and gather information about all the children in each of those families. He must have at least 20 children in his sample. The number of children per family in the U.S. is given in the table below. How many families should Max expect to survey to reach at least 20 children? (treat “5 or more” as 5.)


Describe how you will use a random number table to conduct this simulation.

Trial 1 required 8 families, Trial 2 required 11, and Trial 3 required 11. The mean of these is 10. So our estimate of the number of families needed to get 20 children is ten.
