Please can you help with this problem. The second screenshot is the number 5 question that was made reference to in the third screenshot. Thank you.
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. Atotal 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 day) day) Has documented aggressive acts 5 154 159 . 83 465 548 aggressnve acts Total QUESTION: 1. Calculate the observed sample statistic for this problem. Be sure to use proper notation and round to 3 decimal places. Clearly show your work used to calculate the observed sample statistic.
