Question 3

If the teacher allows students to choose partners for a 1/3 letter grade penalty, what will happen to the student body population.Draw another payoff graph and show the proportion of socialites and individualists on the graph.You cannot use a numerical percentage because the letter grades are not numerically specified.Simply label the horizontal axis with an X at the left side and a Y on the right side and a Z where the proportion of socialites will be fixed.The percentage population then becomes XZ/XY.

Accepted Answer

The answer of If the teacher allows students to choose...
