Answer | | | | | Selected Answer: | False | Correct Answer: | False | | | | | * Question 6 2 out of 2 points | | | The Hurwicz criterion is a compromise between the maximax and maximin criteria. Answer | | | | | Selected Answer: | True | Correct Answer: | True | | | | | * Question 7 2 out of 2 points | | | Using the minimax regret criterion, we first construct a table of regrets. Subsequently, for each possible decision, we look across the states of nature and make a note of the maximum regret possible for that decision. We then pick the decision with the largest maximum regret.

Chapter 3 Risk Identification and Measurement I. Multiple Choice 1. A listing of a random variable’s possible outcomes and the respective probabilities of those outcomes is called the: a. expected value b. standard deviation c. probability distribution d. correlation Answer: c Type: K 2. Multiplying each possible outcome of a random variable by its probability of occurrence, and then adding up these results will be equal to the random variable’s: a. expected value b. standard deviation c. probability distribution d. correlation Answer: a Type: K 3. The graph above depicts the probability distributions for risks A and B.
