2. The National Center on Drug Use and Health reported that, from 2002-2005, 4.8% of persons aged 12 or older used a prescription pain reliever non-medically. Suppose that a random sample of 900 persons aged 12 or older taken this year found 54 that had used a prescription pain reliever non-medically. Test whether the population proportion of persons aged 12 or older using a prescription pain reliever non-medically has increased, using a 1% significance level.
