On Tuesday morning, the student council at a middle school announced its plan to combat the chronic litter problem in the outdoor lunch area: The 16 large trash cans in the lunch area now each have the name of a popular band on them—they are now referred to as Band-Cans. The Band-Can containing the most trash at the end of each day wins; music from that band’s latest release will be played on the school’s public address system in between classes for the next day. The Band-Cans are 42 inches tall; at the end of each day, starting on Monday (to gather baseline data), the members of the student council will use a tape measure to record how full each Band-Can is (0 = Empty . . . 42 = Full).
