Exercise 18
What's in the beer? The Web site Beer100.com advertises itself as "Your Place for All Things Beer." One of their things is a list of 86 domestic beer brands with the percent alcohol, calories per 12 ounces, and carbohydrates per 12 ounces (in grams).
(a) Figure 4.8 gives a scatterplot of carbohydrates versus percent alcohol. Give a short summary of what can be learned from the plot.
(b) One of the points is an outlier. Use the data file to find the outlier brand of beer. How is this brand of beer marketed as compared with the other brands?
(c) Remove the outlier from the data set and generate a scatterplot of the remaining data.
(d) Describe the relationship between carbohydrates and percent alcohol based on what you see in your scatterplot.
