Question 5. "Decision Tree" (15 marks) a) Use the same example of bill's finding a summer job(see the material at your hand) with modified values as below, compute the Expected Monetary Value(EMV) of decision and event nodes (A . B. C. D. E). 1600 1800 Accept Accept A Offer C Reject 2400 Reject 0.05 1800 P=0.6 B E 0.25 1700 0.40 1200 No offer 0.25 O 1-P=0.4 0.05 0.05 2400 0.25 1800 0.40 1700 0.25 1200 0 0.05 Compute the EMV of different nodes. (10 points) EMV(A)= EMV(B)= EMV(C)= EMV(D)= EMV(E)= b) By doing sensitivity analysis of P, compute the critical value P* (the dividing point Bill would change his original optimal strategy).
