A national survey found that 33 of high school students
A national survey found that 33% of high school students said they texted or e-mailed while driving (The Boston Globe, June 8, 2012). These findings came a day after a Massachusetts teenager was convicted for causing a fatal crash while texting. A researcher wonders whether texting or e-mailing while driving is more prevalent among Massachusetts teens. He surveys 100 teens and 42% of them admitted that they texted or e-mailed while behind the wheel. Can he conclude at the 1% significance level that Massachusetts teens engage in this behavior at a rate greater than the national rate?
