Joan, the dorm monitor, told the students in Carnegie Dorm that she would offer the hall that had the best study habits, measured in hours of study, a 70" flat screen TV in the room where they congregate. Knowing that none of the students studied on Sunday, she rolled a die to see which day she would secretly record the number of hours each student studied. Since the die landed on four, she got the above study times for each student on that day. What is the modal time for Carnegie Dorm?
