1. A researcher uses an anonƴmous surveƴ to investigate the television-viewing habits of 100
American adolescents. The researcher plans to make an inference about the television-
viewing habits of all American adolescents based on the results of the surveƴ. The entire
group of American adolescents is an example of a .
