Scenario 1 - Suppose a testing company that administers college entrance exams is
concerned about random guessing. The multiple-choice exams that they administer
contain four choices with only one correct answer. Instead of simply awarding points
for correct answers and zero points for incorrect answers they choose instead to award 9
points for every correct answer and subtract 5 points for every incorrect answer.
Use Scenario 1 to answer the following question. Let's assume that instead of designing
exams with four choices the exams have five choices. How would the penalty for
guessing have to change in order for the student to be indifferent to guessing or leaving
the question blank when he has only eliminated two answers as "incorrect"?
Explain how economists use random experiments.
