McDaniel Condominiums, Inc. of Panama City, FL, recently purchased land near the Gulf of Mexico and is attempting to determine the size of the condominium development it should build. It is considering three sizes of development: Small, d1; Medium, d2; and Large, d3. At the same time, an uncertain economy makes ascertaining the demand for the new condominiums difficult. McDaniel's management realizes that a large development followed by weak demand could be very costly to the company. However, if McDaniel makes a conservative small-development decision and then finds a strong demand, the firm's profit will be lower than it might have been. With three levels of demand-low, medium, and high-McDaniel's management has prepared the following profit (in thousands of dollars) payoff table.

a. If nothing is known about the demand probabilities, what is the recommended decision alternative using Optimistic, Conservative, and Minimax Regret approaches?
b. Suppose the Pr(Weak) = 0.20, Pr(Moderate) = 0.35, and Pr(Strong) = 0.45. Draw a Decision Tree & solve it. What is the recommended decision alternative?
c. What is the expected value of the perfect information (EVPI)?
McDaniel Condominium is considering a 6-month Market Research Survey to learn more about the potential market acceptance of the condominium project. Management anticipates that the market research study will provide either a Favorable or Unfavorable report. Conditional probabilities are shown below.

d. Calculate the Joint and Posterior Probabilities for each State of Nature.
e. Do some research and give at least two real world examples of companies who use decision analysis/theory. Write a paragraph explaining how these companies benefit by using such techniques.
