Question: Suppose that a decision-maker faced with four decision alternatives and four states of nature develops the following payoff table: States of Nature Decision Alternative S1
Suppose that a decision-maker faced with four decision alternatives and four states of nature develops the following payoff table:
| States of Nature | |||
| Decision Alternative | S1 | S2 | S3 |
| D1 | 840,000 | 440,000 | 190,000 |
| D2 | 370,000 | 220,000 | 670,000 |
| D3 | 50,000 | 115,000 | 25,000 |
If the decision maker knows nothing about the probabilities of the four states of nature, what is the recommended decision using the optimistic (maximax), conservative (maximin), and minimax regret approaches?
