Suppose the figures given in this feature are actually only sample data. Would any of the techniques presented in this chapter be appropriate for conducting hypothesis tests to determine if there is a significant difference between Americans and Europeans on the consumption of various beverages? If so, what additional information would be needed?
Can you think of some reasons why Americans consume more carbonated soda pop and beer than Europeans, but less wine, hot or iced tea, or tap water? Do you think that these outcomes may change in time? Why or why not?
