Your report should be structured as follows:

Where are the deer? Random samples of square-kilometer plots were taken in different ecological locations of Mesa Verde National Park. The deer counts per square kilometer were recorded and are shown in the following table.

Shall we reject or accept the claim that there is no difference in the mean number of deer per square kilometer in these different ecological locations? Use a 5% level of significance.

(a) What is the level of significance?

State the null and alternate hypotheses.

H_o: ?₁ = ?₂ = ?₃; H₁: Not all the means are equal.

H_o: ?₁ = ?₂ = ?₃; H₁: Exactly two means are equal.     

H_o: ?₁ = ?₂ = ?₃; H₁: At least two means are equal.

H_o: ?₁ = ?₂ = ?₃; H₁: All three means are different.

(b) Find SS_TOT, SS_BET, and SS_W and check that SS_TOT = SS_BET + SS_W. (Use 3 decimal places.)

Find d.f._BET, d.f._W, MS_BET, and MS_W. (Use 2 decimal places for MS_BET, and MS_W.)

An 88-year-old Chinese-speaking woman is admitted for complaints of dizziness and s/p a syncopal episode while attending a local senior center program. She was brought to the emergency department. She lives with her son and his family in a two-family home, which she owns. She is independent in all activities of daily living (ADLs) and participates in a daily tai chi exercise group with her friends at the local park. She did not want to go to the emergency department, but instead wanted to go home and have some "herbal medicines."

A medical workup reveals that she has aortic stenosis, atrial fibrillation, and hypertension. She is started on an antihypertensive, coumadin, and aspirin and discharged home with her family.

One week later she is readmitted to the hospital with rectal bleeding and bleeding from her gums. She denies taking excessive amounts of coumadin or aspirin. When you ask her son to bring in her medications, only prescribed medications are present, and he reassures you that she is taking the medications according to the physician's orders. She reports that she has not altered her routine at all; she practices tai chi every morning and eats lots of fruits and vegetables. A colonoscopy reveals a polyp, which is removed, and she is transfused with 2 units of packed red blood cells. She is discharged home with her family 2 days later, and home health care is ordered. The home health care nurse visits her 1 day after discharge.

A Chinese-speaking nurse visits her and learns that she is taking all of her prescribed medications as ordered. However, she is taking a supplement of a Chinese herb (gingko biloba) in tablet form twice per day to maintain her memory, and she is also consuming an oriental herbal tea (containing Chinese ginseng, ginger, and garlic) three to four times per day. She states, "I take my pills just like the doctor says, but it is this tea that is making me feel better. It is made of special herbs. It is better than all of those pills." The nurse suggests that the woman stop taking the supplement and drinking the tea until she can find out what herbs it is made of, but she is reluctant to do so because she believes it is the secret to longevity.

1. What actions should the home health nurse take?
2. What information should the nurse include in the medication teaching plan for the patient?
3. Based on the information in the above scenario, do you think that her regimen is causing her rectal bleeding and bleeding gums? Why? Specifically, what elements of her regimen may be contributing to the bleeding?

Please read the case and answer the question at the end of the case.

Title: Last-chance saloon GM prepares to close five factories, attracting Donald Trump’s ire Mary Barra is responding to customers’ soaring appetite for SUVs and pickups

By: Print edition | Business, The Economist.Nov 29th 2018 | NEW YORK

THE CAR industry’s changing fortunes have left a deep mark on Detroit’s urban landscape. Once-bustling factories such as the Fisher body plant, Ford’s Highland Park and the Packard plant became vast, abandoned graphitized shells—a sad reminder of the former might of America’s “motor city”. Now General Motors’s Hamtramck assembly plant looks likely to join the list of closed facilities. On November 26th GM announced that Hamtramck, along with four other factories in North America, and two more unspecified plants elsewhere, would not be assigned new vehicles or components to put together after next year.

News of the cost-cutting initially sent GM’s shares soaring. In total it will trim its North American workforce by a substantial 15%. Another Michigan plant is among those to be idled, as well as facilities in Ohio and Maryland, and in Ontario, Canada. The day after the announcement, however, criticism from President Donald Trump sent shares the other way. Mr Trump tweeted that he was “very disappointed” in Mary Barra, GM’s chief executive, noting that she was not shutting down plants in Mexico or China: “The US saved General Motors, and this is the THANKS we get!” He threatened to cut off GM’s access to federal subsidies for electric cars (although industry-watchers noted that this is not a concern, since GM has mostly used up its permit. Mr Trump is not the only disgruntled politician. Justin Trudeau, Canada’s prime minister, tried to reassure workers about the proposed closure of the plant at Oshawa, on the shores of Lake Ontario, where GM started making cars over half a century ago. After trade liberalisation led to tighter integration of the North American car market, cars became Oshawa’s lifeblood. When the financial crisis pushed GM towards bankruptcy, Canada joined America in bailing out the company to save local jobs.

QUESTION:

The swirl of forces upending the industry means GM probably had little choice but to take some action. As an independent economist, do you agree with the action taken by Ms Mary Barra, GM’s chief executive? Your answer must be supported by the appropriate data and information; and discussed using the appropriate concepts, theories and tools you have learned in Managerial Economics.

1. Jimmy has fallen on hard times recently. Last year he borrowed $250,000 and added an additional $50,000 of his own funds to purchase $300,000 of undeveloped real estate.
