Chapter 21.3, Problem 8E
Consider a variation of the PDC decision tree shown in Figure 21.5. The company must first decide whether to undertake the market research study. If the market research study is conducted, the outcome will either be favorable (F) or unfavorable (U). Assume there are only two decision alternatives d1 and d2 and two states of nature s1 and s2. The payoff table showing profit is as follows:
| State of Nature | ||
| Decision Alternative | s1 | s2 |
| d1 | 100 | 300 |
| d2 | 400 | 200 |
- a. Show the decision tree.
- b. Use the following probabilities. What is the optimal decision strategy?
| P(F) = .56 | P(s1 | F) = .57 | P(s1 | U) = .18 | P(s1) = .40 |
| P(U) = .44 | P(s2 | F) = .43 | P(s2 | U) = .82 | P(s2) = .60 |

An investor is concerned with the market return for the coming year, where the market
return is defined as the percentage gain (or loss, if negative) over the year. The investor believes
there are five possible scenarios for the national economy in the coming year: rapid expansion,
moderate expansion, no growth, moderate contraction, and serious contraction. Furthermore, she
has used all of the information available to her to estimate that the market returns for these
scenarios are, respectively, 23%, 18%, 15%, 9%, and 3%. That is, the possible returns vary from
a high of 23% to a low of 3%. Also, she has assessed that the probabilities of these outcomes are
0.12, 0.40, 0.25, 0.15, and 0.08. Use this information to describe the probability distribution of the
market return.
Compute the following for the probability distribution of the market return for the coming
year.:
1. Mean,
2. Variance,
3. Standard deviation

You are analyzing stocks of three companies you are interested in investing in. Suppose that these three stocks are Apple stock (AAPL), Microsoft (MSFT), and Tesla (TSLA). At the end of this month, each month may move up (increase in value), move down (decrease in value) or stay the same. In this case, an experiment consists of observing the price condition across the three stocks. Each of the three conditions (move up, move down, stay same) are equally likely.
How many outcomes are in the sample space?
List 7 of the outcomes. (use U for move up, D for moving down and S for staying the same)
Let A be the event that all the stocks have the same performance. List the outcomes in A.
Let B be the event that all of stocks are different. List the outcomes in B.
Let C be the event that at least two stocks move up.

The company needs to buy the land before the stadium final decision is made public, in order to save money on the purchase price of the land, which will probably increase substantially when the location for the new stadium is made public. The following payoff table shows profit for a decision analysis problem with four different decision alternatives d1-d4 and two states of nature s1-s2. …payoff written in parentheses means a negative value.

A research survey found that the range of restaurants' profit margins may span between 0% and 15%, and usually restaurants have an average profit margin of 3% to 5%. A restaurant's success is not wholly dependent on the food or drinks it serves, but rather its profit margin is also impacted by a host of other factors like the average cost per customer, type of restaurant operation, among other things. The profit margin data (in percentage) of 13 selected restaurants are 2.3 1.8 2.5 6.1 2.7 5.5 2.3 1.6 Construct a 98% confidence interval for the true profit margin.. 4.8 4.2 4.8 1.9 3.5arrow_forward
