Researchers gathered reports of underage drinking in one particular weekend at different universities. Universities are coded as "dry," meaning that alcohol use is prohibited, or "wet," meaning that alcohol use is allowed after age 21. They are also coded as state schools or private schools. Use these data below and run the appropriate analysis in SPSS. Report and explain the results.
