In: Statistics and Probability
You are considering three investment alternatives for some spare cash: Old Reliable
Corporation stock (A1), Fly-By-Nite Air Cargo Company stock (A2), and a federally insured
savings certificate (A3). You expect the economy will either “boom” (N1) or “bust” (N2), and
you estimate that a boom is more likely (p1 = 0.6) than a bust (p2 = 0.4). Outcomes for
the three alternatives are expected to be (1) $2,000 in boom or $500 in bust for Old Reliable
Corporation; (2) $6,000 in boom, but –$5,000 (loss) in bust for Fly-By-Nite; and (3) $1,200
THE QUESTION IS
5.7 If you have no idea of the economic probabilities pj in Question 5-6, what would be your
decision based on uncertainty using (a) maximax, (b) maximin, (c) equally likely, and (d)
minimax regret assumptions?
