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. Write the equation of the regression line. Interpret the slope and intercept in context. The equation of the regression line is (please do not round): ˆy=____ +____ x The interpretation of the slope is: The p-value for the test is: p≈ The value of R2______ (please leave your answer as a decimal, and round to three places) The interpretation of the value above is:
