Question: Suppose that a decision maker faced with three decision alternatives: d1, d2, d3, and three states of nature: s1, s2, s3, develops the following profit

Suppose that a decision maker faced with three decision alternatives: d1, d2, d3, and three states of nature: s1, s2, s3, develops the following profit payoff table (with profits expressed in $K):

State of Nature
Alternative s1 s2 s3
d1 28 20 10
d2 18 20 22
d3 16 22 26

a) What is the recommended decision using the optimistic approach?

b) What is the recommended decision using the conservative

approach?

c) What is the recommended decision using the minimax regret approach?

d) Assume that the payoff table provides cost rather than profit payoffs. What is the recommended decision using the optimistic, conservative, and minimax regret approaches?
