A manager of a holiday specialty store must determine how many temporary workers to hire for the holiday season. Estimated revenues (thousands of dollars) are based on poor, good, and excellent economic conditions and whether one, two or three workers are hired as follows:
Economic | Condition | ||
Workers Hired | Excellent | Good | Poor |
One | 50 | 50 | 50 |
Two | 100 | 60 | 20 |
Three | 150 | 70 |
-10 |
22. If a Maximax strategy is used, how many workers should be hired?
a. one
b. two
c. three
d. either one or two
e. either two or three
23. If a Maximin strategy is used, how many workers should be hired?
a. one
b. two
c. three
d. either one or two
e. either two or three
24. If an Equally Likely strategy is used, how many workers should be hired?
a. one
b. two
c. three
d. either one or two
e. either two or three
25. If it’s determined that there’s a 20% chance of excellent, 30% chance of good, and 50% chance of poor economic conditions, what’s the expected value of alternative #2--hiring two workers?
a. $16000
b. $26000
c. $46000
d. $48000
e. $50000
26. A Risk Taker (decision maker) would choose the project with
a. The highest Coefficient of Variation
b. The highest Expected Value
c. The highest Standard Deviation
d. The lowest Coefficient of Variation
e. The lowest Standard Deviation
27. A Risk Averse (decision maker) would choose the project with
a. The highest Coefficient of Variation
b. The highest Expected Value
c. The highest Standard Deviation
d. The lowest Coefficient of Variation
e. The lowest Standard Deviation
28. A Risk Neutral (decision maker) would choose the project with
a. The highest Coefficient of Variation
b. The highest Expected Value
c. The highest Standard Deviation
d. The lowest Coefficient of Variation
e. The lowest Standard Deviation
22.The correct answer is option c.three
Max payoff of decision One worker=50
Max payoff of decision Two workers=100
Max payoff of decision Three workers=150
Maximax =Maximum of (maximum pay off of alternatives One worker.Two workers,Three workers)
=Maximum of (50,100,150)
=$ 150 thousands
The appropriate decision will be to hire 3 workers.
23.The correct answer is option a.one
Min payoff of decision One worker=50
Min payoff of decision Two workers=20
Min payoff of decision Three workers=-10
Maximin =Maximum of (minimum pay off of alternatives One worker.Two workers,Three workers)
=Maximum of (50,20,-10)
=$ 50 thousands
The appropriate decision will be to hire one worker.
24.The correct answer is option c.three
In equally likely criterion ,probability of all the three states of nature is same and equal to 1/3
Expected value of alternative one worker=1/3(50+50+50)=50 =$ 50 thousands
Expected value of alternative two workers=1/3(100+60+20)=180/3 =$ 60 thousands
Expected value of alternative three workers=1/3(150+70-10)=210/3 =$ 70 thousands
The appropriate decision will be to hire 3 workers.
25.The correct answer is option d.$ 48000
Expected value of alternative 2 -hiring two workers =0.2*100+0.3*60+0.5*20=$ 48 thousands
26.The correct answer is option b.The highest expected value
