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: Alternatives Machine 1 Machine 2 Machine 3 Machine 4 Machine 5 States of Nature Weather-related cost per hour Cold cost/day Mild cost/day Warm cost/day $42 $45 $40 $60 $45 $40 $42 $35 $30 $40 $45 $47 $54 $48 $45 Using the optimistic criterion, which alternative is best?
