can you help with parts c,d & e specifically? this is the second time I ask this because the last time they were wrong. as you can see the previous answers I put down were wrong.

Seneca 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 approcmately 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 winer 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. Riesling Demand Chardonnay Demand Weak Strong Weak 0.05 0.50 Strong 0.25 0,20 Revenue projections show an annual contribution to profit of $40,000 of Seneca Hit only plants Chardonnay grapes and demand is weak for Chardonnay wine, and $90,000 if the company only plants Chardonnay grapes and demand is strong for Chardonnay wine. 1 Seneca Hill only plants Riesling grapes, the annual profit projection is $45,000 ir demand is weak for Riesling grapes and $65,000 ir demand is strong for Riesling grapes. If Seneca plants both types of grapes, the annual profit projections are as shown in the following table. Riesling Demand Chardonnay Demand Weak Strong Weak $42,000 $60,000 Strong $46,000 $80,000 () Use the expected value approach to recommend which alternative Seneca Hill Winery should follow in order to maximize expected annual profit Ev(Plant Chardonnay) 62500 EV(Plant both grapes) 50000 Ev Plant Riesling) 59000 The best decision is to plant Chardonnay grapes. (a) Suppose management is concerned about the probability assessments when demand for Chardonnay wine is strong. Some believe it is likely for Riesling demand to also be strong in this case. Suppose the probability of strong demand for Chardonnay and weak demand for Riesling is 0.05 and that the probability of strong demand for Chardonnay and strong demand for Riesling is 0.40. How does this change the recommended decision? Assume that the probabilities when Chardonnay demand is weak are still 0.05 and 0.50. Ev(Plant Chardonnay) 02.00 EvePlant both grapes) 00400 Ev(Plant Riesling) BX000 The best decision is to plant both grapes (e) Other members of the management team expect the Chardonnay market to become saturated at some point in the future, causing a fall in prices. Suppose that the annual profit projections fail to $50,000 when demand for Chardonnay is strong and Chardonnay grapes only are planted. Using the original probability assessments, determine how this change would affect the optimal decision. EV(Plant Chardonnay) 44500 x EV(Plant both grapes) 50600 x EV(Plant Riesling) 59000 The best decision is to plant both grapes
