  13. One of you will be randomly selected to be a winner! Pick one: • You can receive $1.00 (cash) right now • You can receive $1.05 (cash) during the next meeting of this class Results: 66% of class took $1 now (but 33% if $1 on next to last day of class instead of last day of class) From DrJamesIII at http://www.youtube.com/watch?v=CnnP0uCqD4k
