Problem 4: Heidi manages a firm that is going to start operating in a new market. She has the option of targeting either "high end" consumers or "low end" consumers. She has some uncertainty regarding actual market conditions in each of these two segments. Very loosely, she thinks that market conditions in each segment could be either "favorable" or "unfavorable." The probability of "favorable" versus "unfavorable" conditions in each market segment (along with her resulting profit in each case) is: Market Condition Probability Profit Favorable p $800,000 High end Unfavorable 1 - p $200,000 Favorable q $500,000 Low end Unfavorable 1 - q $400,000 a. Draw the decision tree for this decision problem. 2 3 b. If $p = \frac{2}{5}$ and $q = \frac{3}{4}$. Which segment should she serve? Explain. c. Suppose $p = \frac{2}{5}$. For what range of q should she serve the "low end" consumers? d. Suppose $q = \frac{3}{4}$. For what range of p should she serve the “low end” consumers?
