One research study of illegal drug use among 12 to 17 year olds reported a decrease in use (from 11.4% in 1997) to 9.7 % now. Suppose a survey in a large high school reveals that, in a random sample of 1,059 students, 95 report using illegal drugs. Use a 0.05 significance level to test the principals claim that illegal drug use in her school is below the current national average.
