A businessman must decide whether to open a new mini grocery branch or simply extend the number of hours of its operation on its existing branch with a payoff of P 150,000. According to his friend, demand at the new location can either be low or high, which the probabilities are estimated to be 35% and 65%, respectively.  If a new branch is opened and demand proves to be low, there is no need to operate on a 24-hr basis but instead, they will stick to 12-hrs operation with a payoff of P 100,000 or enhance marketing strategy through advertising.  Projected response to advertising may either be favorable or not favorable, with estimated probabilities of 40% and 60%, respectively.  If demand is favorable, the payoff grows to P 310,000 and if response is unfavorable, the payoff is P 120,000.  The cost of advertising is P45,000. Required:       a.  Draw a decision tree Determine the expected value for each decision and event nodes. Which alternative is the best for the businessman?

Question
  1. A businessman must decide whether to open a new mini grocery branch or simply extend the number of hours of its operation on its existing branch with a payoff of P 150,000. According to his friend, demand at the new location can either be low or high, which the probabilities are estimated to be 35% and 65%, respectively.  If a new branch is opened and demand proves to be low, there is no need to operate on a 24-hr basis but instead, they will stick to 12-hrs operation with a payoff of P 100,000 or enhance marketing strategy through advertising.  Projected response to advertising may either be favorable or not favorable, with estimated probabilities of 40% and 60%, respectively.  If demand is favorable, the payoff grows to P 310,000 and if response is unfavorable, the payoff is P 120,000.  The cost of advertising is P45,000.
