Based on your experience thus far in this class, what is the probability that you will receive an "A" grade? Explain the factors you have used in arriving at this probability assessment.
We are currently in unit two of our class, The probability of me receiving a “A” grade are very low, I have a higher probability of receiving a low “B” or high “C”. Factors contributing to my probability are through the unit one individual project I could not understand the assignment and I wasn’t able to complete it. Do you believe that all students in your class will arrive at the same probability assessment that you have? Why or why not?

I do not believe all students will arrive at the same probability assessment that I have, I believe this because the probability for myself was low and I believe in my class mates and I believe they can and there’s a high probability they will receive an “A” grade. Explain what is meant by subjective probability. Research the Internet, and provide a business-related example in which subjective probability assessment would likely be used (be sure to cite your sources).

Subjective probability is a personal judgment on whether a certain outcome of a situation will happen or not, this probability is not supported by any type of data or calculations only the personals past experiences and their opinions. In a business scenario a manager may have faith in employees selling skills and assign them to go make a sale with a certain customer, based on past experiences the manager’s opinions on the worker makes him believe in his employees skills. Provide an example of when you have personally used subjective probability assessment or how you might use it in the future.

I recall using subjective probability during sports events; when I go to watch my sons games I have never seen the other team play before but I automatically make the probability of my sons team winning because of my opinions....

...Quantitative Research MethodsQuantitative means quantity which implies that there is something that can be counted. Quantitative research has been defined in many ways. It is the kind of research that involves the tallying, manipulation or systematic aggregation of quantities of data (Henning, 1986)
John W. Creswell defined quantitative research as an inquiry into a social or human problem based on testing a theory composed a theory composed of variables, measured with numbers, and analysed with statistical procedures in order to determine whether the predictive generalisations of the theory holds true. (Creswell, 2003)
On the other hand, another author defined quantitative research as the collection of numerical data in order to explain, predict and/or control phenomena of interest. Quantitative research is explaining phenomena by collecting numerical data that are analysed using mathematically based methods (Aliaga & Gunderson, 2000)
Quantitative research can also be said to be a research based on traditional scientific methods, which generates numerical data and usually seeks to establish causal relationships (or association) between two or more variables, using statistical methods to test the strength and significance of the relationships (A dictionary of Nursing, 2008)
Simply put, quantitative...

Begin your email to AIU by first providing an overview of the database, i.e., a story.
Include the following pieces of information.
Part I
a) What is the gender distribution (%females and %males)?
Solution. From the database, we know that there are 168 female people, 120 male people
among 288 people. So,
168/288=58.33% is female,
120/288=41.67% is male.
b) What is the “tenure with company” distribution by gender?
We look at all males. You can do that for females similarly. We get the following table.
From this table, we know that there are 120 males:
26 with code 2 meaning they stay in the company for 2 to 5 years.”
14 with code 3 meaning they stay in the company over 5 years”
80 with code 1 meaning they stay in the company for less than 2 years
So, the “tenure with company” distribution by male is
26/120=21.67% among 120 males stays in the company for 2 to 5 years.
14/120=11.67% among 120 males stays in the company over 5 years;

Quantitative research collects numerical data through surveys, questionnaires, and polls. Quantitative research main purpose is to find the relationship between two variables. According to Babbie (2010) a descriptive study establishes only associations between variables while experimental defines the casualties (pg. 1). The data that is collected from the research is usually used for bigger representation of a population. The data can also be repeated if it was considered to be very accurate and reliable. Every part of quantitative research is scrutinized very carefully before the data is actually collected. The data that is collected is always in a statistics form or number form. Quantitative research can be used to investigate causal relationships, tell the future, or generalize concepts more widely. According to Babbie (2010) to the main purpose of quantitative research study is to classify features, count them, and construct statistical models in an attempt to explain what is observed (pg. 1). There are four approaches under the Quantitative research and they are descriptive research, correlation research, causal-comparative research, and experimental research.

Question 2 – 10 Points
A gas station near the Emirates Road is revaluating its gasoline-fuel reorder point. The gasoline fuel level in its main tank triggers an automatic replenishment order. The daily demand faced by the station for gasoline is normally distributed with an average of 8,000 liters and standard deviation of 2,500 liters. After the automatic order is placed, the gasoline-fuel is received at the gas station in exactly 3 days. In other words, it takes three days lead time for the gasoline to be replenished after the order has been made. At what volume should the re-order point be set to ensure that the station’s chance of being out of stock during the replenishment period is limited to a probability of 5%? Notes:
Those people who did not score full points on this question usually made it more complicated than it is. ...

Notice a line is uniquely specified by two distinct points. If we draw infinite lines using any two distinct points in the collection, they will all coincide with one another, thereby forming one single line.
Slope: the amount X2 increases given one unit increase of X1
Intercept: the point where the line intersects with X2 axis.

Quantitative Studies on Medication Adherence
Maleah Perdue
University of South Alabama
Introduction
Medication adherence is a significant issue in the health systems of today. Low medication adherence can unnecessarily increase cost of health care and the amount of admissions. According to Conn et al., inadequate medication adherence may account for up to 10% of older adult hospital admissions and may cause up to $100 billion in annual health care cost (2009). Increased medication adherence is likely linked to improved health outcomes while poor medication adherence can lead to exacerbations of disease or even fatality.
Area of Interest
The area of interest is medication adherence in adults that are living in the community. Specifically, older adults that are on multiple medications were looked at because of the increased medication adherence difficulties. There is an increased number of barriers to medication adherence with older adults including poly-pharmacy, comorbidities, vision impairment, hearing loss, and memory deficits among others.
Impact to Practice
Medication non-adherence impacts practice on a daily basis. The studies in these articles are looking to find methods that older adults use to increase medication adherence. Many different methods have a possibility of increasing medication compliance and if these methods could increase adherence the positive effect could be huge in the medical...
