3. The Miramar Company is going to introduce one of three new products: a widget,
a hummer, or a nimnot. The market conditions (favorable, stable, or unfavorable)
will determine the profit or loss the company realizes, as shown in the following
payoff table:
Market Conditions
Favorable
Stable
Unfavorable
Product

Widget
$120,000
$70,000

Hummer

a. Compute the expected value for each decision and select the best one.
b. Develop the opportunity loss table and compute the expected opportunity loss for
each product.
c. Determine how much the firm would be willing to pay to a market research firm to
gain better information about future market conditions.
d. The Miramar Company is considering contracting with a market research firm to do a
survey to determine future market conditions. The results of the survey will indicate
either positive or negative market conditions. There is a 0.60 probability of a positive
report, given favorable conditions; a 0.30 probability of a positive report, given stable
conditions; and a 0.10 probability of a positive report, given unfavorable conditions.
There is a 0.90 probability of a negative report, given unfavorable conditions; a 0.70
probability, given stable conditions; and a 0.40 probability, given favorable
conditions. Using decision tree analysis and posterior probability tables, determine
the decision strategy the company should follow, the expected value of the strategy,
and the maximum amount the company should pay the market research firm for the
survey results.
