Exercise 7-29 Departmental Cost Allocation [LO 7-3]
Robinson Products Company has two service departments (S1 and S2) and two production departments (P1 and P2). The distribution of each service department’s efforts (in percentages) to the other departments is:
| From |
To |
||||||||||
| S1 | S2 | P1 | P2 | ||||||||
| S1 | — | 20 | % | 30 | % | ? | % | ||||
| S2 | 20 | % | — | ? | 40 | ||||||
The direct operating costs of the departments (including both variable and fixed costs) are:
| S1 | $ | 170,000 |
| S2 | 64,000 | |
| P1 | 51,000 | |
| P2 | 125,000 | |
Required:
1. Determine the total cost of P1 and P2 using the direct method.
2. Determine the total cost of P1 and P2 using the step method.
3. Determine the total cost of P1 and P2 using the reciprocal method.

Air traffic controllers perform the vital function of regulating the traffic of passenger planes. Frequently, air traffic controllers work long hours with little sleep. Researchers wanted to test their ability to make basic decisions as they become increasingly sleep deprived. To test their abilities, a sample of 6 air traffic controllers is selected and given a decision-making skills test following 12-hour, 24-hour, and 48-hour sleep deprivation. Higher scores indicate better decision-making skills. The table lists the hypothetical results of this study.
| Sleep Deprivation | ||
|---|---|---|
| 12 Hours | 24 Hours | 48 Hours |
| 24 | 18 | 17 |

2.) Seasonal affective disorder (SAD) is a type of depression during seasons with less daylight (e.g., winter months). One therapy for SAD is phototherapy, which is increased exposure to light used to improve mood. A researcher tests this therapy by exposing a sample of SAD patients to different intensities of light (low, medium, high) in a light box, either in the morning or at night (these are the times thought to be most effective for light therapy). All participants rated their mood following this therapy on a scale from 1 (poor mood) to 9 (improved mood). The hypothetical results are given in the following table.

Wanda of Salty Pawz just doesn’t understand her friend Jamie sometimes. They have been working together since the first dog biscuit came out of the oven, but now that the business is expanding, she can’t seem to get Jamie motivated to compete the tasks she delegates to her. She pays Jamie a salary now, so it’s not like the old days when she was working in exchange for dog treats. She has even given Jamie more responsibility; Jamie now supervises two other employees, a challenge Wanda assumed that Jamie wanted.
One afternoon she stops Jamie in the hallway and asks her if everything is going OK. Jamie responds that things are fine. Later that same week Wanda and Jamie are meeting about an upcoming promotion they are holding at the local animal shelter. Jamie takes a few notes but doesn’t share Wanda’s enthusiasm for the event. Wanda comes right out and asks Jamie if she has lost interest in the business. Jamie shrugs and says no, she is good with everything.
Why do you think Jamie might have lost her motivation and enthusiasm for the business at this point? How could Wanda motivate Jamie more effectively? Make sure the reasons you present are supported by sound motivational theory as established by leaders in the field.
This assignment should be a minimum of one short paragraph and a maximum of two paragraphs. Word totals for this work should be in the range of 200–300 words.

Use for Questions 1-7:
Hector will roll two fair, six-sided dice at the same time. Let A = the event that at least one die lands with the number 3 facing up. Let B = the event that the sum of the two dice is less than 5.
1. What is the correct set notation for the event that “at least one die lands with 3 facing up and the sum of the two dice is less than 5”?
2. Calculate the probability that at least one die lands with 3 facing up and the sum of the two dice is less than 5.
3. What is the correct set notation for the event that “at least one die lands with 3 facing up if the sum of the two dice is less than 5”?
4. Calculate the probability that at least one die lands with 3 facing up if the sum of the two dice is less than 5.
5. What is the correct set notation for the event that “the sum of the two dice is not less than 5 if at least one die lands with 3 facing up”?
6. Calculate the probability that the sum of the two dice is not less than 5 if at least one die lands with 3 facing up. 7. Are A and B independent? Explain your reasoning.
Use for question 10: A particular type of scan is used to try to determine whether brain tumors are cancerous or not. Each time a tumor is scanned, the result is reported as either “positive”, “negative” or “inconclusive”. Among tumors that are cancerous, 68% of scans are “positive”, 28% of scans are “inconclusive”, and 4% of scans are “negative”. Among tumors that are NOT cancerous, 60% of scans are “negative”, 37% of scans are “inconclusive” and 3% of scans are “positive”. Historically, among all brain tumors, 67% are not cancerous.
10. If a tumor is scanned and the result is labeled as “inconclusive” what is the probability that the tumor is not cancerous?

Suppose there are two firms in a market who each simultaneously choose a quantity.Firm 1's quantity is q1, and firm 2's quantity is q2. Therefore the market quantity is Q= q1+q2. The market demand curve is given by P=130-Q. Also, each firm has constant marginal cost equal to 25. There are no fixed costs. Marginal revenue of the firms are given by MR1=130-2q1-q2 & MR2=130-q1-2q2.
A) How much output will each firm produce in the Cournot equilibrium ?
B) What will be the market price of the good?
C) What is DWL that results from this duopoly?
D) How much profit does each firm make?
E) Suppose Firm 2 produced 20 units of output. How much output should Firm 1 produce in order to maximize profit?
