The manager of a cinema with multiple theaters randomly surveyed customers about whether they would prefer to view a new movie in a regular or a​ 3-D theater. Suppose a population of customers contains 100 adults and 25 children. If a representative sample from this population contains 12​ adults, how many children should the sample​ contain? Explain. The ratio of adults to children in the population is nothing​: nothing. ​So, the ratio of adults to children in a representative sample should be nothing​: nothing. There should be nothing children in the sample.
