Is there a link between watching television and aggressive acts in teenagers? A random sample of families with teenagers was obtained from two counties in upstate New York. A total of 707 teenagers (one from each family) participated in the study. The study compared the amount of TV watched by the teens in a typical day (classified as either minimal (less than one hour per day) or moderate (more than one hour per day)), to whether the teenager had committed any aggressive acts (according to school and police reports). A two-way table of the data is shown below.
