Tully Tyres sells cheap imported tyres. The manager believes its profits are in decline. You have just been hired as an analyst by the manager of Tully Tyres to investigate the expected profit over the next 12 months based on current data.

•Monthly demand varies from 100 to 200 tyres – probabilities shown in the partial section of the spreadsheet below, but you have to insert formulas to ge the cumulative probability distribution which can be used in Excel with the VLOOKUP command.
•The average selling price per tyre follows a discrete uniform distribution ranging from $160 to $180 each. This means that it can take on equally likely integer values between $160 and $180 – more on this below.
•The average profit margin per tyre after covering variable costs follows a continuous uniform distribution between 20% and 30% of the selling price.
•Fixed costs per month are $2000.

(a)Using Excel set up a model to simulate the next 12 months to determine the expected average monthly profit for the year. You need to have loaded the Analysis Toolpak Add-In to your version of Excel. You must keep the data separate from the model. The model should show only formulas, no numbers whatsoever except for the month number.

The first random number (RN 1) is to simulate monthly demands for tyres.
•The average selling price follows a discrete uniform distribution and can be determined by the function =RANDBETWEEN(160,180) in this case. But of course you will not enter (160,180) but the data cell references where they are recorded.
•The second random number (RN 2) is used to help simulate the profit margin.
•The average profit margin follows a continuous uniform distribution ranging between 20% and 30% and can be determined by the formula =0.2+(0.3-0.2)*the second random number (RN 2). Again you do not enter 0.2 and 0.3 but the data cell references where they are located. Note that if the random number is high, say 1, then 0.3-0.2 becomes 1 and when added to 0.2 it becomes 0.3. If the random number is low, say 0, then 0.3-0.2 becomes zero and the profit margin becomes 0.2.
•Add the 12 monthly profit figures and then find the average monthly profit.

Show the data and the model in two printouts: (1) the results, and (2) the formulas. Both printouts must show the grid (ie., row and column numbers) and be copied from Excel and pasted into Word. See Spreadsheet Advice in Interact Resources for guidance.

(b)Provide the average monthly profit to Ajax Tyres over the 12-month period.

(c)You present your findings to the manager of Ajax Tyres. He thinks that with market forces he can increase the average selling price by $40 (ie from $200 to $220) without losing sales. However he does suggest that the profit margin would then increase from 22% to 32%.

He has suggested that you examine the effect of these changes and report the results to him. Change the data accordingly in your model to make the changes and paste the output in your Word answer then write a report to the manager explaining your conclusions with respect to his suggestions. Also mention any reservations you might have about the change in selling prices.

The report must be dated, addressed to the Manager and signed off by you.

Please SOLVE EXERCISE 4.20

Programming Exercise 3.20 required you to design a PID manager that allocated a unique process identifier to each process.

Exercise 4.20 requires you to modify your solution from Exercise 3.20 by writing a program that creates a number of threads that requested and released process identifiers. Modify your solution to Exercise 4.20 by ensuring that the data structure used to represent the availability of process identifiers is safe from race conditions. Use Pthreads mutex locks.

Questions:

Wenatchee is a town on a large river. On the other side of the river is East Wenatchee (since the river is the county line, these are in two different counties and thus, two different cities.) Wenatchee (which I refuse to call "West Wenatchee") is pretty much hemmed in on all sides by mountains. East Wenatchee, on the other hand, sits on a large plateau surrounded by wheat fields.

Assume that housing in Wenatchee and housing in East Wenatchee are what economists call "perfect substitutes." This means basically that people don't care whether they live in Wenatchee or East Wenatchee. Then imagine that in the nearest big city there is a pandemic followed by a bunch of riots. Part of the town is taken over by Marxists revolutionaries. The city starts dismantling the police and raising taxes because they have no money. (Just try to imagine it!) and this causes a lot of people to decide it would be nice to live in a smaller town on the other side of the mountains.

Which will grow more, Wenatchee or East Wenatchee? Why? Your answer should include econ words like "supply," "demand," "quantity supplied," "quantity demanded," and a certain important word from chapter 5. It should also probably include a graph or two.

Robert Campbell and Carol Morris are senior vice-presidents of the Mutual ofChicago Insurance Company. They are co-directors of the company’s pension fund management division. A major new client has requested that Mutual of Chicago present an investment seminar to illustrate the stock valuation process. As a result, Campbell and Morris have asked you to analyze the Bon Temps Company, an employment agency that supplies word processor operators and computer programmers to businesses with temporarily heavy workloads. You are to answer the following questions.

-Assume that Bon Temps is expected to experience supernormal growth of 30% for the next 3 years, then to return to its long-run constant growth rate of 6%. What is the stock’s value under these conditions? What are its expected dividend yield and its capital gains yield in Year 1? In Year 4?

-Suppose Bon Temps is expected to experience zero growth during the first three years and then to resume its steady-state growth of 6% in the fourth year. What is the stock’s value now? What are its expected dividend yield and its capital gains yield in Year 1? In Year 4?

The Sarbanes Oxley (SOX) Act was passed in 2002 as a result of corporate scandals and in as attempt to regain public trust in accounting and reporting practices. Two random samples of 1015 executives were surveyed and asked their opinion about accounting practices in both 2000 and in 2006. The table below summarizes all 2030 responses to the question, “Which of the following do you consider most critical to establishing ethical and legal accounting and reporting practices?” Did the distribution of responses differ from 2000 to 2006?

1. Determine and state whether this is a test of Goodness of Fit, a test of homogeneity or a test of association (or independence). Include in your statement a justification for your choice.
2. Write the correct Null and Alternate Hypotheses for the test
3. Perform the test using Minitab (remember to include the output in your Word document)
4. State your decision, and why you made this choice
5. Give a conclusion in the context of the problem. If you make the decision to reject the null hypothesis, be sure to comment on the bar chart.

Conceptual Frameworks for the Study of Health Policy and Law

Following are three conceptual frameworks for the study of health policy and laws:

Framework one consists of three broad topical domains—health care policy and law, bioethics, and public health policy and law.

Framework two consists of three historically dominant perspectives—social, political, and economic perspectives.

Framework three consists of key stakeholders in the process.

In this assignment, you will focus on the government's health's immunization laws that were passed to protect children from infectious diseases.

Using South University Online Library or the Internet, search articles on the frameworks of study of health policy and law in the areas of immunization of children.

On the basis of your research and your understanding, write a 3- to 4-page APA formatted essay in a Microsoft Word document. Your essay should cover all the three frameworks mentioned above. You need to pick one of the three stakeholders from both framework one and two. Use a minimum of five stakeholders for framework three.

You will be required to use a minimum of three scholarly sources that includes a title page and a separate reference page.

Electric Youth, Inc. (EY) is a perfume manufacturer. The company is interested in buying a new perfume-filling machine to make a new type of perfume as a separate project for the firm. The new machine costs $1,000,000 and they typically use the straight-line method to depreciate their assets. They believe that with the new machine, revenues from this particular type of perfume will increase by $650,000 per year. Operating costs (not including depreciation) associated with the machine are estimated to be $300,000 per year. The project is expected to last for five years; this is also the useful life of the machine. When the project is complete, they plan to recycle the machine (which means it has a zero salvage value at the end of its useful life). They would need to make an immediate investment in inventory of $25,000, which would be unwound in the terminal year of the project. The tax rate for the firm is 22%. To do:

a) Calculate the cash flows (years 0 to 5) for this investment. You can do this in Excel if you would like (cut and paste into the Word document).

b) Given a cost of capital of 11%, calculate the NPV of this project. Show your work. Is this a good investment? Why or why not?
