eneca Hill Winery recently purchased land for the purpose of establishing a new vineyard. Management is considering two varieties of white grapes for the new vineyard: Chardonnay and Riesling. The Chardonnay grapes would be used to produce a dry Chardonnay wine, and the Riesling grapes would be used to produce a semidry Riesling wine. It takes approximately four years from the time of planting before new grapes can be harvested. This length of time creates a great deal of uncertainty concerning future demand and makes the decision concerning the type of grapes to plant difficult. Three possibilities are being considered: Chardonnay grapes only; Riesling grapes only; and both Chardonnay and Riesling grapes. Seneca management decided that for planning purposes it would be adequate to consider only two demand possibilities for each type of wine: strong or weak. With two possibilities for each type of wine it was necessary to assess four probabilities. With the help of some forecasts in industry publications management made the following probability assessments. Chardonnay DemandRiesling Demand WeakStrong Weak0.050.50 Strong0.250.20 Revenue projections show an annual contribution to profit of $30,000 if Seneca Hill only plants Chardonnay grapes and demand is weak for Chardonnay wine, and $80,000 if the company only plants Chardonnay grapes and demand is strong for Chardonnay wine. If Seneca Hill only plants Riesling grapes, the annual profit projection is $35,000 if demand is weak for Riesling grapes and $55,000 if demand is strong for Riesling grapes. If Seneca plants both types of grapes, the annual profit projections are as shown in the following table. Chardonnay DemandRiesling Demand WeakStrong Weak$32,000$50,000 Strong$36,000$70,000 Develop a decision tree. (Enter monetary values in thousands and percentages in decimal form.)
