    QUESTION 1

    Imagine that the United States is preparing for the outbreak of an unusual Asian disease, which is expected to kill 600 people. Two alternative programs to combat the disease have been proposed. Assume that the exact scientific estimates of the consequences of the programs are as follows:

    Program A: If program A is adopted, 200 people will be saved.

    Program B: If program B is adopted, there is a one-third probability that 600 people will be saved and a two-thirds probability that no one will be saved.

    Which of the two programs would you favor, A or B?

    Program A
    Program B

    Now, for the same problem, decide which of the two options you would favor:

    Program C: If program C is adopted, 400 people will die.

    Program D: If program D is adopted, there is a one-third probability that no one will die and a two-thirds probability that 600 people will die.

    Program C
    Program D

    For each of the following five items, write down your best estimate in the center column without looking up any information. Next, put a lower and upper bound around your estimate, such that you are 95% confident that your range surrounds the actual quantity. In other words, your range should be wide enough that there is a 95% chance the truth lies inside it.

    Imagine that you personally hired a new salesperson, Brad. Two other members of your department wanted to hire someone else, but you talked them into hiring Brad, in part due to his strong recommendation from a friend of yours. Brad's sales for his first month are somewhat disappointing. You have made significant investments in his training. Should you fire him?

    Suppose you decide to give Brad more time to prove himself. You give him a pep talk and he promises you that he will do better.

    After another month, Brad still isn't meeting his sales target. He comes to you to apologize and outlines his strategy for bringing up his numbers. His strategy seems sound. Do you fire Brad or give him another chance?

    Give him another chance
    Fire him
