Question

A town has 10,000 two-child families. Design a simulation to estimate the percentage of two-child families with two girls. Choose a simulation tool, explain one trial, and describe the headings for a table in which you would record the outcomes.

Answer 1

Given is a town has 10,000 two-child families. The town should be divided by smaller units and then conduct a survey on these units to account for the number of two-child families per unit. Combine the number per unit and divide by the total population of the town. Construct a table containing the name of the units and the number of two-child family per unit. 

Answer 2

Correct answer

The simulation tool could be a coin flip, with heads up representing a girl and tails up representing a boy. One trial would require flipping the coin twice. One table would show the outcome of two coin tosses as tally marks, and indicate whether the results were boy-boy, boy-girl, or girl-girl.
