Question

Question 1. A plant manager is considering buying additional stamping machines to accommodate increasing demand. The alternatives are to buy 1 machine, 2 machines, or 3 machines. The profits realized under each alternative are a function of whether their bid for a recent defense contract is accepted or not. The payoff table below illustrates the profits realized (in $000's) based on the different scenarios faced by the manager.

  

Alternative

Bid Accepted

Bid Rejected

 

Buy 1 machine

$10

$5

 

Buy 2 machine

$30

$4

 

Buy 3 machine

$40

$2

Using the information above, which alternative should be chosen based on the maximax criterion?

Buy 1 machine

Buy 2 machines

Buy 3 machines

Question 2. A plant manager is considering buying additional stamping machines to accommodate increasing demand. The alternatives are to buy 1 machine, 2 machines, or 3 machines. The profits realized under each alternative are a function of whether their bid for a recent defense contract is accepted or not. The payoff table below illustrates the profits realized (in $000's) based on the different scenarios faced by the manager.

Alternative Bid Accepted Bid Rejected 

Buy 1 machine $10 $5 

Buy 2 machines $30 $4 

Buy 3 machines $40 $2 

Refer to the information above. Assume that based on historical bids with the defense contractor, the plant manager believes that there is a 65% chance that the bid will be accepted and a 35% chance that the bid will be rejected.

Question 4. Assume that you have an urn containing 10 balls of the following description:

4 are white (W) and lettered (L)

2 are white (W) and numbered (N)

3 are yellow (Y) and lettered (L)

1 is yellow (Y) and numbered (N)

If you draw a numbered ball (N), the probability that this ball is white (W) is 0.60.

True

False

Question 5. What is the formula for the break-even point of a simple profit model?

Fixed cost / variable cost per unit

(Selling price per unit — variable cost per unit) / fixed cost

Fixed cost / (selling price per unit —variable cost per unit)

Fixed cost / (variable cost per unit —selling price per unit)

Selling price per unit — (fixed cost / variable cost per unit)
