The birth rate in many countries is falling. This will create problems in the future because there will be less people contributing taxes and more retired people receiving government pensions. The birth rate needed to maintain current population levels is 2.08 children per woman. The General Social Survey asked “How many children have you ever had?” Conduct a test to determine whether the mean number of children is less than 2.08 (CHILDS).

In 2013, the population of the United States was 316,427,395, the number of Americans 18 and over was 242,823,652, and the number of households was 123,460,000. (Source: Factfinder.census.gov) Use a 95% confidence level unless otherwise specified.
