Question: The schools' most serious problem. Results from a Gallup Youth Survey reveal that teens most often mention "violence, fighting, and school safety" when asked to name the biggest problem their schools must deal with. The report of this sample survey of 600 teens found that, with 95% confidence, between 9% and 17% of all teens believe that "violence, fighting, and school safety is the most serious problem facing their schools." Explain to someone who knows no statistics what the phrase "95% confidence" means in this report.
