CASE STUDY
Adult and Pediatric Primary Care (APPC), a five-doctor clinic with 40 employees and two offices, is a financially viable, growing organization with an expanding patient base. The practice is five years old, started by two physicians who left a larger group with a goal to provide high-quality care. At the time they started, they hired an experienced medical office manager, a front-desk receptionist, and two medical assistants. Over the past five years, they have added more physicians and staff as patient volumes grew. The physician owners are very cautious about adding cost to the operation, always making sure that patient revenues could appropriately cover their overhead. At a recent practice meeting that included the physician owners and the office manager, the agenda included a discussion point about adding a human resources professional to the administrative team. The office manager indicated that she was spending a significant amount of her time dealing with HR-related duties at the expense of her other duties, such as bill ing management, vendor negotiations, and shopping for an electronic medical records system. Although she felt that she was skilled at hiring and training, she did not feel her competencies included, at the level necessary, the other areas of HR such as legal compliance, performance management, and benefits and compensation management. Consequently, she was recommending hiring an individual with those skills. The physician owners generally agreed with her recommendation but voiced concern about the additional expense of adding a non- revenue-producing staff member and wanted more detail as to what an HR professional would do for a practice their size. The meeting was adjourned without making a final decision regarding adding the HR staff member pending more research by the office manager on the specific duties the HR professional would perform and a cost–benefit analysis on the position.
1. Describe the potential value a human re-sources professional could bring to APPC.

For a healthy human, a body temperature follows a normal distribution with Mean of 98.2 degrees Fahrenheit and Standard Deviation of 0.26 degrees Fahrenheit. For an individual suffering with common cold, the average body temperature is 100.6 degrees Fahrenheit with Standard deviation of 0.54 degrees Fahrenheit. Simulate 10000 healthy and 10000 unhealthy individuals and answer questions 14 to 16.
14. If person A is healthy and person B has a cold, which of the events are the most likely? Pick the closest answer.
15. What would be a range [A to B], which would contain 68% of healthy individuals? Pick the closest answer.
16. What is the approximate probability that a randomly picked, unhealthy individual (one with the cold) would have body temperature above 101 degrees Fahrenheit? Pick the closest answer.
A random experiment was conducted where a Person A tossed five coins and recorded the number of “heads”. Person B rolled two dice and recorded the sum the two numbers. Simulate this scenario (use 10000 long columns) and answer questions 10 to 13.
10. Which of the two persons (A or B) is more likely to get the number 4?
11. Which of the two persons will have higher Median among their outcomes?
12. What is the probability that person B obtains number 5 or 6?
13. Which of the persons has higher probability of getting the number 3 or smaller?

Water is an essential element of life on earth. A human being can survive for only about one week without water. As the global population expands and increasing industrialization creates ever-growing demands for water, supply of this vital commodity has become endangered. Just as water, clean air is an essential element for the survival of life on earth. Air that is polluted can endanger our health and cause damage to trees, wildlife, and property.
Using the Internet, research on the topic, "Various Health Hazards Caused by Water and Air Pollution.
"Based on your understanding, create a 3- to 4-page Microsoft Word document that includes the answers to the following questions:
What are the hazardous substances that may be found in drinking water and what are their impacts on our health?
Describe how water is made safe for human consumption.
Epidemiologic analyses have demonstrated a correlation between an increase in total daily mortality and an increase in air pollution. Provide examples to explain how historically significant fatal air pollution episodes (that were characterized by extreme increases in air pollution) lead to increase in mortality.
Describe how greenhouse gases contribute to the greenhouse effect.
Explain the term "global warming" and present arguments in favor of and against the proposition that global warming has occurred during the past century. What environmental outcomes have been attributed to global warming?

The COVID-19 pandemic is first and foremost a human tragedy. Measures introduced to deal with the pandemic could save lives but are having wide-ranging economic effects and inducing economic contagion. Greater focus is needed on the transmission mechanisms of the economic contagion and how assessments of the economic impacts are made.
Q1 Assess the impacts of Covid-19 outbreak on regional trading agreements such as ASEAN and European Union.
Q2 Discuss the impacts of Covid-19 crisis on global financial market and the role of International Monetary Fund (IMF) in overcoming the crisis.

Assume the duration of human pregnancies can be described by a Normal model with mean 266 days and standard deviation 16 days. 1. What percentage of pregnancies should last between 270 and 280 days? 2. At least how many days should be the longest 25% of all pregnancies last? 3. Suppose a certain obstetrician is providing prenatal care to 60 pregnant women. According to the Central Limit Theorem, if we calculated sample means, what is the mean and standard deviation of the distributions of these sample means? 4. What is the probability that the mean duration of these patients’ pregnancies will be less than 260 days?

Nucleotide Pairs
The human genome is composed of the four DNA nucleotides: A, T, G, and C.
Some regions of the human genome are extremely G–C rich (i.e., a high proportion of the DNA nucleotides there are guanine, G, and cytosine, C).
Other regions are relatively A–T rich (i.e., a high proportion of the DNA nucleotides there are adenine, A, and thymine, T).
Imagine that you want to compare nucleotide sequences from two regions of the genome.
Sixty percent of the nucleotides in the first region are G–C (30% each of guanine and cytosine) and 40% are A–T (20% each of adenine and thymine).
The second region has 25% of each of the four nucleotides.
If you choose a single nucleotide at random from each of the two regions, what is the probability that they are the same nucleotide? (Hint: Where X is any of the 4 DNA nucleotides calculate Pr(X|X) for all four and sum.)
On a separate sheet draw a probability tree (first branch will have 4 limbs).
Assume that nucleotides over a single strand of DNA occur independently within regions and that you randomly sample a two-nucleotide sequence from each of the two regions. List all the possible 2-nucleotide sequences for each region and their probabilities (include pairs like XX and assume XY is the same as YX):
First region pairs:
Second region pairs:
What is the probability that the two pairs chosen from different regions are the same?

A natural disaster destroy a significant part of the Republic of Amazonia. There were a high number of death, besides widespread destruction of infrastructure and capital. Analyze the short run and long run economic effect of this adverse event.
C:.
The Republic of Rainland has a small, open economy. A new president was sworn in recently. Determined to raise the country’s population above poverty, he doubled the money supply. What is the short run and long run effect on domestic prices, output and exchange rate?
D:
The Republic of Amazonia is having a recession due to a fall in export demand. The chief economic advisor of the President made the following statement:
“The recession causes an increase in unemployment rate from 3% to 6% and a drop in GDP of 5%. While unfortunate, these are the only costs of the economic downturn. Our society could bear them easily. Therefore, the government should do nothing and let the economy recover by itself in due time.”
Do you agree with the analysis and proposal of the economic advisor?

Human measurements provide a rich area of application for
statistical methods. In a longitudinal study the development of
elementary school children explored the relationship between IQ and
private speech. Private speech is considered to be when children
talk to themselves. It was thought that private speech would be
related to IQ, because IQ is supposed to measure mental maturity,
and it was known that private speech decreases as students progress
through the primary grades. The study included 34 students whose
first-grade IQ scores are given below.
