Question:

A media report claims that more than 75% of middle school students engage in bullying behavior. A University of Illinois study on aggressive behavior surveyed a random sample of 558 middle school students. When asked to describe their behavior in the last 30 days, 445 students admitted that they had engaged in physical aggression, social ridicule, teasing, name-calling, and issuing threats—all of which would be classified as bullying. Do these data provide convincing evidence at the α=0.05 significance level that the media report’s claim is correct?
