You are playing a single joint game with all your fellow students where you have to choose an integer from (0,1,2, .100}. A player's payoff depends on the distance of his answer to 2/3 of the average of all players' answers; the closer the better. Example: Your answer is 45. There are two other players whose answers are 25 and 56. Then, the average is (45+25+56)/3=42. 2/3 of the average is 28. Your distance to 2/3 of the average is 145-28|=17. All players will be ranked according to their answer's proximity to 2/3 of the average. The top 25% of the players get 2 points. The next 50% get 1 point. The bottom 25% get 0 points. (In case of ties, points will be distributed evenly in the enlarged classes.) Please give your answer as a single integer from (0,1,2,3,.100}. A valid submission would look like this: 45
