Instructions

Choose a number between 0 and 100. You will win and get the chance to execute the trade according to your preferences if your chosen number is closest to two-thirds (2/3) times the average of all chosen numbers of the people in your class.

Put differently: All participants decide on a number in the given interval. The average is calculated from all the chosen numbers. This average is multiplied by 2/3. This number is the number being searched, and whoever's guess is closest to this number wins.

You will have 3 minutes to insert your guess. The experimenter will inform you when the 3 minutes are over.

PLEASE NOTE:

Three Buyers and three Sellers will be the winners of this round

The winners will have the chance to trade according to their preferences after all three rounds are completed

One of those three rounds will be randomly selected

The winners of that round will be compensated according to their preferences

"Losers" will not trade if the round is to be selected - Sellers will NOT be able to keep their chocolate bar!

This means: "Losers" that own a chocolate bar must give it back to the experimenter!
