What is the Expected Value of Perfect Information (EVPI)? (5 pts) Select one: O a. EVPI = $38,500 O b. EVPI = $55,000 O c. EVPI = $54,000 O d. EVPI = $48,000 Oilco must determine whether or not to drill for oil in the South China Sea. It costs $90,000 to drill for oil. If oil is found, the revenue is estimated to be $700,000. At present, Oilco believes there is a 40% chance that the field contains oil. Before drilling, Oilco can hire (for $20,000) a geologist to obtain more information about the likelihood that the field will contain oil. There is a 70% chance that the geologist will issue a favorable report and a 30% chance of an unfavorable report. Given a favorable report, there is an 60% chance that the field contains oil. Given an unfavorable report, there is a 10% chance that the field contains oil. Determine the optimal strategy, the expected profit, EVSI and EVPI. What is the Expected Value of Sample Information (EVSI)? (5 pts) Select one: O a. EVSI = $41,000 O b. EVSI = $42,000 O c. EVSI = $26,000 O d. EVSI = $20,000
