1. Section 3.1, Exercise #14, p. 125 Finding Probabilities consider a company that selects employees for random drug tests. The company uses a computer to select randomly employee numbers that range from 1 to 6296. Find the probability of selecting a number greater than 1000.

P(E) = Number of outcomes in E / Total number of Outcomes in sample space Number of outcomes in E = 6296 – 100 = 5296
The probability = P(E) = 5296 / 6296 = 0.841 = 84.1% There is an 84.1 percent probability of selecting a number greater than 1000 2. Section 3.1, Exercise #20, p. 126 Using a Frequency Distribution to Find Probabilities in use the frequency distribution, which shows the number of American voters (in millions) according to age.

18 to 20 years old 4.8
21 to 24 years old 7.3
25 to 34 years old 20.4
35 to 44 years old 28.4
45 to 64 years old 43.7
Find the probability that a voter chosen at random is between 35 and 44 years old.
Probability = 28.4 / (4.8 + 7.3 + 20.4 + 28.4 + 43.7 + 24.9) = 0.2193 = 21.93% 3. Section 3.2, Exercise #16, p. 136 A doctor gives a patient a 60% chance of surviving bypass surgery after a heart attack. If the patient survives the surgery, he has a 50% chance that the heart damage will heal. Find the probability that the patient survives and the heart damage heals.

Let BS be the event that the patient survives bypass surgery. Let H be the event that the heart damage will heal.
Then P(BS) = 0.60, and also we have a conditional probability: given the patient survives the probability that the heart damage will heal is 0.5, that is P(H|BS) = 0.5 We want to know P(BS and H).

Using the formula of the conditional probability:
P(H and BS) = P(H|BS)·P(BS) = (0.6)(0.5) = 0.3
That is the probability that the patient survives and the heart damage...

1. Explain the nursing clinical role, as indicated in Exhibits 7.1, 7.2, and 7.3. A competing perspective is much more limited. In extreme form, it might be limited to completion of tasks indicated by patient management protocols and physicians’ orders. All other functions would be assigned to other units of the organization or left undone. Discuss why this broad view is preferable, in terms non-nursing stakeholders, such as trustees, physicians, or patients, might appreciate.
Nursing organizations must provide five functions including delivering excellent care, coordinating and monitoring interdisciplinary care, educating patients, families, and communities, maintaining the nursing organization, and improving nursing performance. Nurses provide a safe, effective, patient centered, timely, efficient, and equitable contribution in delivering excellent care. They’re able to deliver this quality of care by implementing the nursing process; a system of assessing patients, diagnosing individual nursing care needs, planning care, implementing plans, and evaluating care. A broad view is preferable to design, implement, and evaluate patient care by coordinating, delegation, and supervising the care provided by the healthcare team.
2. Describe how the long-term need for nurses is determined and the shift-by-shift variation in need accommodated? (See also Chapter 8, Additional QFD 2.6.)

3. Are the following statements true or false? Please explain why.
a. The only way a company can grow at a rate above its current sustainable growth rate is by issuing new stock?
False. A company could grow its sustainable growth rate by increasing any of the four rates above their sustainable rate which include its profit margin (increase sales, quicker asset turnover, decrease in debts, increase in financial leverage) or in their retention ratio. The problem is that there are limits to a company’s ability to increase these ratios.
b. The stock market is a ready source of new capital when a company is incurring heavy losses?
False. Expecially in our current market people tend to invest cautiously, unless they have a lot of ready capital to invest ,which is unlikely, to buy stocks, and the company would have to ensure they are not using this as their only means of ready capital and that asset turnover remains steady while ensuring a minimal amount of loss – while waiting for this new source to pay off.
c. Share repurchases usually increase earnings per share.
True. repurchasing stock reduces the number of shares outstanding and that contributes to the increased earnings per share. The cost of repurchasing those outstanding shares is a cost the company has to absorb and will reflect on the balance sheet and income...

Homework Assignment for Week4:
For Week4, please complete the following for Joe’s Fly-By-Night Oil Company, whose financial statements are shown below:
• Prepare a ratio analysis for the fiscal year ended Dec 31, 2012. Organize your analysis per the following outline:
(1) Liquidity
- Current ratio: 25,000/17,000=1.47%
Quick ratio: 25,000-17,000/17,000=25,000
Comments on liquidity- The results cant really determine how well or bad the company is doing until you compare it to another company. This ratio helps show the ability to pay off short term obligations as they are due.
(2) Asset management
- Total Asset turnover: 10,000/40,000=.25
Average collection period (ACP): 10,000/365=27
3,000/27=111 days
Comments on asset management- Each $1 of asset is producing .25 in sales. Using assest utilization shows why one firm turns over assests more rapied than another. Average collection period states that it’s taking the customer around 111days to pay off their bills. This indicates how long sales stay on companys books.
(3) Debt management
- Debt ratio: 20,000/40,000=50%
Times interest earned: 3,000/200=15 times
Comments on debt management- Times interest earned shows the number of times that income before interest and taxes covers the interest obligation . The higher the...

This paper extrapolates from data taken from the Real Estate Data Set that reviewed 105 homes. The data set reviewed several points of homes sold in the year 2005. The real estate data included such data as the selling price, number of bedrooms, square footage of the homes, and the number of bathrooms of each home (Lind, Marchal, & Wathen, 2008).
The data analysis includes calculation of the measures of central tendency, dispersion, and skew of the selling price. The calculations analyzed 30 homes with the lowest and highest home prices of $139,900 to $345,300.

Consequentialism, Deontology, and Virtue Ethics
The philosophies of consequentialism, deontology, and virtue ethics are guidelines for decision making that utilize very different theories of how an ethical dilemma should be approached. Consequentialism is a philosophy that asks whether or not the end justifies the means. “In other words, an act and therefore a decision is ethical if its favorable consequences outweigh its negative consequences” (Brooks, 2007, p. 329). Deontology, on the other hand, uses the principle of “do unto others as you would have them do unto you.” If you don’t want someone to lie to you, you should not lie to others (Brooks, 2007, p. 331). Virtue ethics are more inherent to the character of the person making the decision and are considered to be the moral fiber of a person. “Dispositions that are often cited as virtues include: honesty, integrity, enlightened self-interest, compassion, fairness, impartiality, generosity, humility, and modesty” (Brooks, 2007, p. 333).
In the case of a mayor trying to decide whether or not to allow a new developer to come to town because doing so will cause a loss of jobs and displaced senior citizens, the consequentialism view proposes the good of bring hundreds of jobs and economic growth outweighs the loss of a few jobs and senior center. I believe this is an ethical business decision because it is taking into consideration the good of the entire town. The senior center can...
