C F DECISION TREE G H ELI Faces two possible decisions: introduce the NEW product globally at a cost of $850,000 or evaluate it in a North American test market at a cost of $200,000. If it introduces the product globally, ELI might find either a high or low response to the product. The probabilities of these events are estimated to be 0.6 and 0.4, respectively. With a high response, gross revenues of $2,000,000 are expected; with a low response, the figure is $450,000. If ELI starts with a North American test market, it might find a low response or a high response, with probabilities of 0.3 and 0.7, respectively. This may or may not reflect the global market potential. In any case, after conducting the marketing research, ELI next needs to decide whether to keep 2 sales only in North America, market globally, or drop the product. If the North 3 American response is high and ELI stays only in North America, the expected revenue is $1,200,000. If it markets globally (at an additional cost of $200,000), the 5 probability of a high global response is 0.9 with revenues of $2,000,000 ($450,000 s if the global response is low). If the North American response is low and it remains 7 in North America, the expected revenue is $200,000. If it markets globally (at an 8 additional cost of $600,000), the probability of a high global response is 0.05, with 9 revenues of $2,000,000 ($450,000 if the global response is low). o Construct a decision tree, determine the optimal strategy
