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 (classied 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. Minimal TV Moderate TV (Less than one hour per (At least one hour per Total day) day) Has documented aggressive acts No documented aggressive acts Total QUESTIONS: If researchers are interested in knowing whether there is a difference in the proportion of teenagers committing aggressive acts when comparing minimal TV watching to moderate TV watching... 1.
