Question: Do Beer Drinkers and Liquor Drinkers Have different BAC levels? The sample data in the following list show BAC (blood alcohol concentration) levels at arrest of randomly selected jail inmates who were convicted of DWI or DUI offenses. The data are categorized by the type of drink consumed (data from Department of Justice). Test the claim that beer drinkers and liquor drinkers have the same BAC levels. Based on the result, do both groups seem equally dangerous, or is one group more dangerous than other?
