Beer and blood alcohol content: Many people believe that gender, weight, drinking habits, and many
other factors are much more important in predicting blood alcohol content (BAC) than simply considering
the number of drinks a person consumed. Here we examine data from sixteen student volunteers at Ohio
State University who each drank a randomly assigned number of cans of beer. These students were evenly
divided between men and women, and they differed in weight and drinking habits. Thirty minutes later, a
police officer measured their blood alcohol content (BAC) in grams of alcohol per deciliter of blood
(Malkevitc and Lesser, 2008). The scatterplot and regression table summarize the findings.
