The Center on Budget and Policy Priorities (www.cbpp.org) reported that average out-of-pocket medical expenses for prescription drugs for privately insured adults with incomes over 200% of the poverty level was $173 in 2002.Suppose an investigation was conducted in 2012 to determine whether the increased availability of generic drugs,Internet prescription drug purchases,and cost controls have reduced out-of-pocket drug expenses.The investigation randomly sampled 196 privately insured adults with incomes over 200% of the poverty level,and the respondents' 2012 out-of-pocket medical expenses for prescription drugs were recorded.These data are in the file Drug Expenses.Based on the sample data,can it be concluded that 2012 out-of-pocket prescription drug expenses are lower than the 2002 average reported by the Center on Budget and Policy Priorities? Use a level of significance of 0.01 to conduct the hypothesis test.
