The file DomesticBeer2 contains the number of calories per 12 ounces and number of carbohydrates (in grams) per 12 ounces for a sample of 15 of the best-selling domestic beers in the United States. (Data extracted from www.beer100.com/beercalories. htm.)
a. Visually evaluate the number of calories per 12 ounces for each beer by constructing a bullet graph. For the purposes of comparison, consider calories below 100 as low, between 100 and 160 as medium, and above 160 as high.
b. Visually evaluate the number of carbohydrates (in grams) per 12 ounces for each beer by constructing a bullet graph. For the purposes of comparison, consider carbohydrates below 10 grams as low, between 10 and 14 grams as medium, and above 14 grams as high.
c. What preliminary conclusions can you reach about the number of calories and carbohydrates in the beers?
d. Why would constructing sets of gauges for the calories and carbohydrates be a less effective means of visualizing these data?
