Data for the average size of a soda (in ounces) at all thirty major league baseball parks are as follows: 14, 18, 20, 16, 16, 12, 14, 16, 14, 16, 16, 16, 14, 32, 16, 20, 12, 16, 20, 12, 16, 16, 24, 16, 16, 14, 14, 12, 14, 20. Compute descriptive statistics for this variable including a box and whisker plot. Comment on the results. Presuming the first 15 are drink sizes in the American League and the last 15 are drink sizes in the National League, test the hypotheses: Soft drink sizes are larger at American League Ball Parks than at National League Ball Parks. Do the data represent a sample or a census?
