PRACTICE ANOTHER three states of nature. table shows profit for a dacia- analysis problem with two decision alternatives and The probat...ues ror the states of nature are P(s1)=0.65,P(s2)=0.15, and P(s3)=0.2. (a) What is the optimal decision strategy if perfect information were available? If s1 then if s2 then If s3 then (b) What is the exnected value for the decision strategy developed in part (a)? (c) Using the expected value approach, what is the recommended decision without perfect information? What is its expected value? The recommended decision without perfect information is EV= (d) What is the expected value of perfect information? EVPI=
