A plant manager considers the operational cost per hour of five machine alternatives. The cost per hour is sensitive to three potential weather conditions: cold, mild, and warm. The following table represents the operations cost 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? $6.6 $3.2 $5.8 $1.6 SUMMARY OUTPUT Consider the output shown in Table 4.1. The Mean Square value is missing.
