Question Finicky Jewelers sells watches for $50 each. During the next month, they estimate that they will sell 15, 25, 35, or 45 watches with respective probabilities of 0.35, 0.25, 0.2, and 0.2 They can only buy watches in lots of ten from their dealer. 10, 20, 30, 40, and 50 watches cost $40, 39, 37, 36, and 34 per watch respectively. Every month, Finicky has a clearance sale and will get rid of any unsold watches for $24 (watches are only in style for a month and so they have to buy the latest model each month). Any customer that comes in during the month to buy a watch, but is unable to, costs Finicky $6 in lost goodwill. A payoff table has been created as follows. Demand 15 Demand 25 Demand 35 Demand 45 -110 300 O Given that the payoff values are profits, which of the alternatives should the manager choose if she uses the following decision criterion: Maximax, Maximin, Equal likelihood, Hurwicz (a = 0.3), Minimax regret and expected opportunity loss?
