a) The correct decision tree (with EMVs rounded to the nearest whole number)for Deborah is shown in Figure 2 b) To maximize the return, Deborah's decision should be to Winter Park Technologies The EMV of selected alternative for Deborah = s[] (enter your answer as a whole number and include a minus sign if nedossary). FIGURE 1 Deborah Kellogg buys Breathalyzer test sets for the Denver Police Department. The quality of the test sets from her two suppliers is indicated in the following table: Probability for Percent Probability for Winter Dayton Defective Park Technology Enterprises 1% 0.70 0.25 3% 0.25 0.30 5% 0.05 0.45 1% D(0.70) Buy from Winter Park 3% (0.25) -82 -48 -144 -240 5% D(0.05) 5 -82 1% (0.25) -48 163 3% D(0.25) - 144 + $37 Buy from Dayton 240 For example, the probability of getting a batch of tests that are 1% defective from Winter Park Technology is 0.70. Because Kellogg orders 12,000 tests per order, this would mean that there is a 0.70 probability of getting 120 defective tests out of the 12,000 tests if Winter Park Technology is used to fill the order. A defective Breathalyzer test set can be repaired for $0.40. Although the quality of the test sets of the second supplier, Dayton Enterprises, is lower, it will sell an order of 12,000 test sets for $37 less than Winter Park. a) The correct decision tree (with EMVs rounded to the nearest whole number for Deborah is shown in 5% 0.45) D = Defective Rate FIGURE 2 19 D(0.70) -48 Buy from Winter Park FIGURE 2 1% D(0.70) Buy from Winter Park 3% D(0.25) - 82 - 48 - - 144 - 240 5% D(0.05) - 82 1% D(0.25) - 48 + $37-163 3% D(0.30) - 144 Buy from Dayton - 240 5% D(0.45) D = Defective Rate FIGURE 3 1% D(0.70) Buy from Winter Park 3% D(0.25) - 82) - 48 - 144 - 240 5% D(0.05) -82 1% D(0,25) - 48 - 144 + $37 3% D(0.25) - 163 Buy from Dayton 5% D(0.45) - 240 D = Defective Rate
