A hundred players are participating in this game (N = 100). Each player has to choose an integer between 1 and 100 in order to guess “5/6 of the average of the responses given by all players”. Each player who guesses the integer closest to the 5/6 of the average of all the responses, wins. (a) Find all weakly dominated strategies (if any). (b) Find all strategies that survive the Iterative Elimination of Dominated Strategies (IEDS) (if any). No additional...

Iterated
Iterated elimination of dominated strategies:
Eliminate all strictly (weakly) dominated strategies for all
players in the original game.
Eliminate all strictly (weakly) dominated strategies for all
players in the modified game where players cannot choose any
strategy that was eliminated at Step 1.
3 Eliminate all strictly (weakly) dominated strategies for all
players in the modified game where players cannot choose any
strategy that was eliminated at Steps 1 and 2.

A group of 7 players play the following game. Each writes down a positive integer that is less than 1000. The player who writes down the smallest number is awarded a prize equal to the number of dollars equal to the number that she wrote down. If there is a tie for smallest number, the prize is divided equally among those who wrote the smallest number. Find the strategy or strategies that survive iterated deletion of strictly dominated strategies. Explain...
