Problem 13-14 (Algorithmic) The following profit payoff table shows profit for a decision analysis problem with two decision alternatives and three states of nature: State of Nature Decision Alternative S1 S2 S3 d1 250 100 100 d2 200 100 150 The probabilities for the states of nature are P(s1) = 0.45, P(s2) = 0.25 and P(s3) = 0.3. What is the optimal decision strategy if perfect information were available? S1 : S2 : S3 : What is the expected value for the decision strategy developed in part (a)? If required, round your answer to one decimal place. Using the expected value approach, what is the recommended decision without perfect information? What is its expected value? If required, round your answer to one decimal place. What is the expected value of perfect information? If required, round your answer to one decimal place.

Suppose that you are given a decision situation with three
possible states of nature: S1,
S2, and S3. The prior
probabilities are P(S1) = 0.17,
P(S2) = 0.53, and
P(S3) = 0.30. With sample information
I, P(I | S1) = 0.13,
P(I | S2) = 0.04, and
P(I | S3) = 0.19. Compute the
revised or posterior probabilities:
P(S1 | I),
P(S2 | I), and
P(S3 | I). If required, round
your answers to four decimal places.
