Lecture Examples
Example 149: Disney is comparing two methods of receiving customers at its City Halls in the Magic Kingdom and Disney Land. They are deciding if using one long line (used in Disney Land) is better than allowing people to line up in separate lines for each teller (used in Magic Kingdom).
