Exam 20: Decision Making

SCENARIO 20-1 The following payoff table shows profits associated with a set of 3 alternatives under 2 possible states of nature. -Referring to Scenario 20-1,if the probability of S1 is 0.5,then the expected monetary value (EMV )for A1 is

SCENARIO 20-6 A student wanted to find out the optimal strategy to study for a Business Statistics exam with scores out of 100 possible points.He constructed the following payoff table based on the mean amount of time he needed to study every week for the course and the degree of difficulty of the exam.From the information that he gathered from students who had taken the course,he concluded that there was a 40% probability that the exam would be easy. -Referring to Scenario 20-6,the optimal strategy using the return-to-risk ratio criterion is to study 8 hours per week on average for the exam.

SCENARIO 20-2 The following payoff matrix is given in dollars. Suppose the probability of Event 1 is 0.5 and Event 2 is 0.5. -Referring to Scenario 20-2,what is the best action using the maximax criterion?

Blossom's Flowers purchases roses for sale for Valentine's Day.The roses are purchased for $10 a dozen and are sold for $20 a dozen.Any roses not sold on Valentine's Day can be sold for $5 per dozen.The owner will purchase 1 of 3 amounts of roses for Valentine's Day: 100,200,or 400 dozen roses.Given 0.2,0.4,and 0.4 are the probabilities for the sale of 100,200,or 400 dozen roses,respectively,then the optimal EOL for buying roses is
