-1 Give an example of a good decision that you made that resulted in a bad outcome. Also give an example of a bad decision that you made that had a good outcome. Why was each decision good or bad?
3-1. The purpose of this question is to make students use a personal experience to distinguish between good and bad decisions. A good decision is based on logic and all of the available information. A bad decision is one that is not based on logic and the available information. It is possible for an unfortunate or undesirable outcome to occur after a good decision has been made. It is also possible to have a favorable or desirable outcome occur after a bad decision.
3-3 What is an alternative? What is a state of nature?
3-3. An alternative is a course of action over which we have complete control . An example of an alternative is deciding whether or not to take an umbrella to school or work on a particular day . A state of nature is an event or occurrence in which we have no control.. An example of a state of nature is whether or not it will rain on a particular day.
Discuss the differences among decision making under certainty, decision making under risk, and decision making under uncertainty.
3-4. The basic differences between decision-making models under certainty, risk, and uncertainty depend on the amount of chance or risk that is involved in the decision. A decision-making model under certainty assumes that we know with complete confidence the future outcomes. Decision-making-under-risk models assume that we do not know the outcomes for a particular decision but that we do know the probability of occurrence of those outcomes. With decision making under uncertainty, it is assumed that we do not know the outcomes that will occur, and furthermore, we do not know the probabilities that these outcomes will occur
What techniques are used to solve decision-making problems under uncertainty? Which technique results in an optimistic decision? Which technique results in a pessimistic decision
3-5. The techniques discussed in this chapter used to solve decision problems under uncertainty include maximax, maximin, equally likely, criterion of realism, and minimax regret. The maximax decision-making criterion is an optimistic decision-making criterion, while the maximin is a pessimistic decision-making criterion
Define opportunity loss. What decision-making criteria are used with an opportunity loss table?
3-6. For a given state of nature, opportunity loss is the difference between the payoff for a decision and the best possible payoff for that state of nature. It indicates how much better the payoff could have been for that state of nature. The minimax regret and the minimum expected opportunity loss are the criteria used with this
3-7 What information should be placed on a decision tree?
3-7. Alternatives, states of nature, probabilities for all states of nature and all monetary outcomes (payoffs) are placed on the decision tree. In addition, intermediate results, such as EMVs for middle branches, can be placed on the decision tree
-8 Describe how you would determine the best decision using the EMV criterion with a decision tree
3-8. Using the EMV criterion with a decision tree involves starting at the terminal branches of the tree and working toward the origin, computing expected monetary values and selecting the best alternatives. The EMVs are found by multiplying the probabilities of the states of nature by the economic consequences and summing the results for each alternative. At each decision point, the best alternative is selected.
