CH 16 Decision Theory A chain of ski equipment shops purchases skis from a manufacturer each summer for the coming winter season. The most popular intermediate model costs $150 and sells for $250. Any skis left over at the end of the winter are sold at the store's spring sale (for $100). Sales over the years have been quite stable. Gathering data from all its stores, the chain developed the given probability distribution for demand. The manufacturer will take orders only for multiples of 20, so the chain is considering the following order sizes: 160, 180, 200, 220, 240. Complete parts a through c below. a. Construct a payoff table for the ski equipment chain's decision problem of how many pairs of skis to order. What is the best decision from an expected value basis? Type integers or decimals. Do not round. Demand Order 150 175 200 225 250 - X 160 $ $ $ $ Probability distribution for demand 180 200 220 Demand Probability 150 0.15 240 175 0.34 200 0.29 225 0.16 250 0.06 Print Done
