BUS 660 Topic 4 Midterm Exam
- Question: Which of the methods for decision making best protects the decision maker from undesirable results?
- Question: If there is a maximum of 4,000 hours of labor available per month and 300 ping-pong balls (xi) or 125 wiffle balls (x?) can be produced per hour of labor, which of the following constraints reflects this situation?
- Question: Problem 4-05 (Algorithmic) In American football, touchdowns are worth 6 points. After scoring a touchdown, the scoring team may subsequently attempt to score 1 or 2 additional points. Going for 1 point is virtually an assured success, while going for 2 points is successful only with probability p. Consider the following game situation. The Temple Wildcats are losing by 14 points to the Killeen Tigers near the end of regulation time. The only way for Temple to win (or tie) this game is to score two touchdowns while not allowing Killeen to score again. The Temple coach must decide whether to attempt a 1-point or 2-point conversion after each touchdown. If the score is tied at the end of regulation time, the game goes into overtime. The Temple coach believes that there is a 43% chance that Temple will win if the game goes into overtime. The probability of successfully converting a 1-point conversion is 1.0. The probability of successfully converting a 2-point conversion is p.
- Assume Temple will score two touchdowns and Killeen will not score. Create a decision tree for the decision of whether Temple’s coach should go for a 1- point conversion or a 2-point conversion after each touchdown. The terminal nodes in the decision tree should be either WIN or LOSE for Temple.
- Assume that a WIN results in a value of 1.0 and LOSE results in a value of 0. Further, assume that the probability of converting a 2-point conversion is p = 28%. Should Temple’s coach go for a 1-point conversion or 2-point conversion after scoring the first touchdown?
- Question: Problem 1-15 (Algorithmic) Preliminary plans are underway for construction of a new stadium for a major league baseball team. City officials question the number and profitability of the luxury corporate boxes planned for the upper deck of the stadium. Corporations and selected individuals may purchase a box for $325000. The fixed construction cost for the upper-deck area is estimated to be $4500000, with a variable cost of $150000 for each box constructed.
- What is the breakeven point for the number of luxury boxes in the new stadium?
- Preliminary drawings for the stadium show that space is available for the construction of up to 47 luxury boxes. Promoters indicate that buyers are available and that all 47 could be sold if constructed. What is your recommendation concerning the construction of luxury boxes?
- Question:When production volume exceeds the breakeven point, we can expected
- Question:A negative dual price indicates that increasing the right-hand side of the associated constraint would be detrimental to the objective.
- Question:When the exponential distribution probability is given as P(x<9) = l-e -9 18 the average value for x is
- Question:Because the dual price represents the improvement m the value of the optimal solution per unit increase in right-hand-side, a dual price cannot be negative
- Question: Problem 2-11 (Algorithmic) Let A be an event that a person’s primary method of transportation to and from work is an automobile and B be an event that a person’s primary method of transportation to and from work is a bus. Suppose that in a large city P{A) = 0.46 and P{B} = 0.37.
-
- Are events A and B mutually exclusive?
- Find the probability that a person’s primary method of transportation is some means other than a bus. If required, round your answer to two decimal places.
- Question:If P(A U B) = P(A) + P(B), then A and B are mutually exclusive.
- Question:A posterior probability associated with sample information is of the form
- Question:One measure of the accuracy of a forecasting model is the
- Question:The dual price for a < constraint
- Question:In situations where you need to compare forecasting methods for different time periods, the most appropriate accuracy measure is
- Question:Z is a standard normal random variable. What
