A plant manager considers the operational cost per hour of five machine Jalternatives. The cost per hour is sensitive to three potential weather conditions: cold, mild, and warm. The following table represents the cost of the operations per hour for each alternative-state of nature combination. Assume that for a randomly selected day, there is a 30% probability of cold weather, 50% probability of mild weather, and 20% probability of warm weather. What is the EVPI?
