4. A chain of supermarkets requires 24,000 fluorescent light bulbs for its stores. There are two suppliers of these bulbs. Supplier A offers them at $4.00 per bulb and will replace any defectives with guaranteed good ones for $4.00 each. Supplier B offers them at $4.15 per bulb and guarantees to replace defectives for $1.00 each. The probability distributions of the percentage of defective bulbs from the two suppliers, listed in Table 8,7, have been estimated from historical data. For example, the probability is 0.4 that 5%, or 1200, of the 24,000 bulbs will be defective if they are purchased from supplier A. The supermarket plans to sell these bulbs for $4.40 apiece and charge nothing for replacement of defectives. Which supplier should be chosen in order to maximize the supermarket’s EMV? .Click here for more on this paper.......
