At the text’s website there is a data set that provides the number of calories per 12 ounces of beer and the percentage alcohol for several different brands of beer.
a. Refer to the scatterplot that follows. Is a linear analysis appropriate? Why or why not?
b. Remove the two low-end outliers (the beer with 0.0% alcohol and the beer with 0.4% alcohol), because most of the data come from alcoholic beers. Do a complete analysis of the data to help predict the calorie content based on the percent alcohol. Include the graph, equation, interpretation of slope and intercept, and coefficient of determination. (Source:, accessed via StatCrunch. Owner: Webster West)
