It is generally accepted that the mean heart rate (beats per minute; bpm) of an adult human is between 65 bpm and 75 bpm, with a single average value of 72 bpm. In this case study you will test the hypothesis that the average heart rate of adults is 72 bpm (μ = 72 bpm) for all adults and then separately by gender. The distribution of heart rates is approximately normal.

1.Complete the hypothesis test for all adults(Males and Females) by performing the following steps. Use a 5% level of significance.You may assume that σ = 7.035bpm.

A.Determine if you should use a Z-Test or t-Test in conduct this hypothesis test.Explain your decision.

B.State the null and alternative hypothesis.Identify the claim.

C.Calculate the Standardized Test Statistic.

D.Calculate the p-value (or the Critical Value(s)).

E.State your decision. Explain how you made this decision.

F.State your conclusion in the context of the problem.

2.If you lowered the level of significance to 1%(in # 1), would your decision change? Explain your reasoning

Creative problem solving.

Scenario #2:  

The rate of growth in the US economy is currently 0.5% annually. Your mission is to increase our growth rate to at least 4% annually, without setting off unacceptable levels of inflation. You have the tools of fiscal and monetary policy available.

Q1. Present your solution to the problem – write it down.  

Strategy for creating your solution:

--First identify a specific natural resource and think through how having more of it or a better quality of it could lead to significantly increasing the GDP growth rate.  

--This will lead you to a general solution to the problem.

--Write it down! The explanation of the solution should take at least one good paragraph!

--Determine what will be required to make the solution happen, typically it is money.

--Think of ways to use your fiscal and monetary policy tools to get the needed money.

--To attack the problem you must select at least one Monetary Policy tool and one Fiscal Policy tool.

Q2. Write down the name(s) of the one fiscal policy tool and the one monetary policy tool that you picked.

--Remember – for this question you need one Fiscal Policy tool and one Monetary Policy tool.

Q3. Explain why you picked the tools that you picked, and why you did not select the other choices.

--Specifically explain, what is good about the tool you selected and what is not so good about the tools you did not select? Do this for both the monetary and fiscal policy tool that you selected. The key here is to use some decisin criteria in making your choice.

Q4. Thoroughly and completely explain how your solution would work to solve the problem. You must include and explain the use of your monetary and fiscal policy tools and indicate the impact your solution would have on the key economic variables. Please present your answer using a chain of events format. Be specific. I need to see the detail.

Please Answer all of the questions. Thanks :)

Need one fiscal policy and one monetory policy.

The word "euthanasia" draws its roots from Greek meaning "good death." As it is used in this discussion, it means "the act of ending the life of a person suffering from either a terminal illness, or an incurable disease." The American Medical Association (AMA) is against physicians assisting in euthanasia. Only a small number of states allow for euthanasia. Euthanasia advocates stress that it should be allowed as an extension of a person's autonomy. Those who are against euthanasia often say that it can lead to the devaluation of human life and to a slippery slope, in which the old and disabled will be killed on the whims of healthy people.

Consider the following case:

A woman was diagnosed with a motor neuron disease (the same disease that Stephen Hawking had) five years ago. This is a condition that destroys motor nerves, making control of movement impossible, while the mind is virtually unaffected. People with motor neuron disease normally die within four years of diagnosis from suffocation due to the inability of the inspiratory muscles to contract. The woman's condition has steadily declined. She is not expected to live through the month and is worried about the pain that she will face in her final hours. She asks her doctor to give her morphine for pain if she begins to suffocate or choke. This will lessen her pain, but it will also hasten her death.

1. Is the short amount of time she has to live ethically relevant? What is ethical difference between a patient dying in 6 hours, dying in a week and dying in a year?

2. Is the right for a patient's self-determination powerful enough to create obligations on the part of others to aid her so that she can exercise her rights? She clearly cannot kill herself (she can't move), but should a medical professional be obligated to help her?

3. Should the money used to care for this woman be taken into account when she is being helped? Will people feel that they need to end their lives earlier to save money? Explain.

4. If you were the physician, what would you do? If you pass her off to another doctor knowing he or she would do it, does this free you from your ethical obligations? Why

Assume that adults were randomly selected for a poll. They were asked if they​ "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human​ embryos." Of those​ polled, 488 were in​ favor, 399 were​ opposed, and 121 were unsure. A politician claims that people​ don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 121 subjects who said that they were​ unsure and use a 0.01 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5. What does the result suggest about the​ politician's claim?

Identify the null and alternative hypotheses for this test. Choose the correct answer below.

A.

Upper H 0​: p = 0.5

Upper H 1​: p < 0.5

B.

Upper H 0​: p = 0.5

Upper H 1​: p ≠ 0.5

C.

Upper H 0​: p ≠ 0.5

Upper H 1​: p = 0.5

D.

Upper H 0​: p = 0.5

Upper H 1​: p > 0.5

Identify the test statistic for this hypothesis test. ​(Round to two decimal places as​ needed.)

Identify the​ P-value for this hypothesis test. ​(Round to three decimal places as​ needed.)

Identify the conclusion for this hypothesis test.

A. Reject Upper H 0. There is sufficient evidence to warrant rejection of the claim that the responses are equivalent to a coin toss.

B. Reject Upper H 0. There is not sufficient evidence to warrant rejection of the claim that the responses are equivalent to a coin toss.

C. Fail to reject Upper H 0. There is not sufficient evidence to warrant rejection of the claim that the responses are equivalent to a coin toss.

D. Fail to reject Upper H 0. There is sufficient evidence to warrant rejection of the claim that the responses are equivalent to a coin toss.

What does the result suggest about the​ politician's claim?

A. The result suggests that the politician is doing his best to accurately portray the feelings of the people.

B. The results are inconclusive about whether the politician is correct or not.

C. The result suggests that the politician is correct in claiming that the responses are random guesses equivalent to a coin toss.

D. The result suggests that the politician is wrong in claiming that the responses are random guesses equivalent to a coin toss.

A 2006 report of the U.S. Surgeon General states that "there is no risk-free level of exposure to secondhand smoke. Nonsmokers exposed to secondhand smoke at home or work increase their risk of developing heart disease by 25 to 30 percent and lung cancer by 20 to 30 percent. The finding is of major public health concern due to the fact that nearly half of all nonsmoking Americans are still regularly exposed to secondhand smoke."

Consider the following data from the U.S. Department of Health and Human Services, National Center for Health Statistics, Third National Health and Nutrition Examination Survey. All values are measured levels of serum cotinine (in ng/ml), a metabolite of nicotine—when nicotine is absorbed by the body, cotinine in produced.

Smokers = subjects reported tobacco use

ETS = nonsmokers exposed to environmental tobacco smoke at home or work

No ETS = nonsmokers with no exposure to environmental tobacco smoke at home or work

Use a Kruskal-Wallis test with a 0.05 significance level to test the claim that the median cotinine levels are not all equal for these three groups. What do the results suggest about secondhand smoke?

Billingham Packaging is considering expanding its production capacity by purchasing a new​ machine, the​ XC-750. The cost of the​ XC-750 is $2.79 million.​ Unfortunately, installing this machine will take several months and will partially disrupt production. The firm has just completed a $46,000 feasibility study to analyze the decision to buy the​ XC-750, resulting in the following​ estimates:

•​Marketing: Once the​ XC-750 is operational next​ year, the extra capacity is expected to generate $10.05 million per year in additional​ sales, which will continue for the​ 10-year life of the machine.

•​Operations: The disruption caused by the installation will decrease sales by $4.96 million this year. As with​ Billingham's existing​ products, the cost of goods for the products produced by the​ XC-750 is expected to be 69% of their sale price. The increased production will also require increased inventory on hand of $1.14 million during the life of the​ project, including year 0.

•Human​ Resources: The expansion will require additional sales and administrative personnel at a cost of $1.95 million per year.

•​Accounting: The​ XC-750 will be depreciated via the​ straight-line method over the​ 10-year life of the machine. The firm expects receivables from the new sales to be 14% of revenues and payables to be 10% of the cost of goods sold.​ Billingham's marginal corporate tax rate is 35%.

a. Determine the incremental earnings from the purchase of the​ XC-750.

b. Determine the free cash flow from the purchase of the​ XC-750.

c. If the appropriate cost of capital for the expansion is 9.8%​, compute the NPV of the purchase.

d. While the expected new sales will be $10.05 million per year from the​ expansion, estimates range from $8.10 million to $12.00 million. What is the NPV in the worst​ case? In the best​ case?

e. What is the​ break-even level of new sales from the​ expansion? What is the breakeven level for the cost of goods​ sold?

f. Billingham could instead purchase the​ XC-900, which offers even greater capacity. The cost of the​ XC-900 is $4.05 million. The extra capacity would not be useful in the first two years of​ operation, but would allow for additional sales in years 3 through 10. What level of additional sales​ (above the $10.05 million expected for the​ XC-750) per year in those years would justify purchasing the larger​ machine?

A. The following probability table contains a list of events that two companies stated as reasons for eliminating jobs in the United States.    

What is the probability that a randomly selected US job was neither eliminated by Company B nor eliminated because of outsourcing?

B. An Ear, Nose and Throat (ENT) medical practice collected information on 200 patients who had throat illnesses the previous year. The study investigated whether the cause of their illnesses was either bacterial or viral. The observed frequencies are shown in the following table.    

What is the probability that a randomly selected patient had a bacterial throat illness given that the patient had pharyngitis?

C. The following table summarizes the number of cavities of 600 elementary students who live in districts within the city that either fluoridate or do not fluoridate their water supply.    

What is the probability that a randomly selected student has 2 cavities given that he/she lives in a district with fluoridated water?

D. The accounting and human resource (HR) departments of a large company recently hired 35 new employees. The departments recorded how long it took newly hired employees to earn a raise. The data are summarized in the following frequency table.   

What is the probability that a randomly selected new employee earned a raise in 6 months given that he/she works in the accounting department?

Please explain each step because Im very confused with all of it, thank you!

The state of Glottamora has $100 million remaining in its budget for the current year. One alternative is to give Glottamorans a one-time tax rebate. Alternatively, two proposals have been made for state expenditures of these funds. The first proposed project is to invest in a new power plant, costing $100 million and having an expected useful life of 20 years. Projected benefits of the new power plant are as follows:

Years 1-5 Benefits per Year 0
Years 6-20 Benefits per Year 20

The second alternative is to undertake a job retraining program, also costing $100 million and generating the following benefits:
Years 1-5 Benefits per Year ($ Millions) 20
Years 6-10 Benefits per Year ($ Millions) 14
Years 11-20 Benefits per Year ($ Millions) 4

The state Power Department argues that a 5 percent discount factor should be used in evaluating the projects because that is the government’s borrowing rate. The Human Resources Department suggests using a 12 percent rate because that more nearly equals society’s true opportunity rate. The present value interest factor at the end of years from 0 - 20 for the two discount rates are given in the following table.

Evaluate the projects using both the 5 % and the 12 percent rates:

Net Benefits at Discount Rate = 5% Net Benefits at Discount Rate = 12%
Project ($ Millions)    Select One    ($ Millions) Select One
Power Plant _____________________ -18.2, 62.7, -22.7, 81.5 ___________________________ -18.2, -22.7, 62.7, 81.5
Job Retraining Program _____________________ 35.0, 53.1, 8.0, -6.2   ___________________________ 53.1, 8.0, -6.2, 35.0

Judy Anderson was assigned as a recruiter for South Illinois Electric Company (SIE), a small supplier of natural gas and electricity for Cairo, Illinois, and the surrounding area. The company had expanded rapidly during the last half of 1990s, and the growth was expected to continue. In January 2003 SIE purchased the utility system serving neighbouring Mitchell Country. This expansion concerned Judy. The company workforce had increased by 30 percent the previous year, and Judy had found it a struggle to recruit enough qualified job applicants. She knew that the expansion would intensify the problem.

Judy is particularly concerned about meter readers. The task required in meter reading are relatively simple, a person drives to homes served by the company, finds the gas or electric meter, and records its current reading. If the meter has been tempered with, it is reported. Otherwise, no decision-making of any consequence is associated with the job. The readers perform no calculations. The pay was $8.00 per hour, high for unskilled work in the area. Even so, Judy had been having considerable difficulty keeping the 37 meter readers’ positions filled.

Judy was thinking about how to attract more job applicants when she received a call from a human resource director, Sam McCord. “Judy”, Sam said, “I’m unhappy with the job specification calling for only high school education for meter readers. In the planning for the future, we need better educated people in the company. I’ve decided to change the education requirement for the meter reader job from a high school diploma to a college degree.”

“but, Mr. McCord”, protested Judy, “the company is growing rapidly. If we are to have enough people to fill those jobs, we just can’t insist on finding college applicants to perform such a basic task. I don’t see how we can meet our future needs for this job with such an unrealistic job qualification.”

Sam terminated the conversation abruptly by saying, “No, I don’t agree. We need to upgrade all the people in our organization. This is just part of a general effort to do that. Anyway, I cleared this with the president before I decided to do it.”

To share 3 points, 3 paragraphs on your opinion about Sam's effort to upgrade the people in the organisation.
