You are a supervisor at Regional Call Center’s Washington, D.C., facility. Regional provides contract call center services for several companies, including banks and major retail companies. You have been with the company for slightly more than seven years, having joined Regional right after graduating with a master’s degree in business administration from Strayer University. After the monthly staff meeting, you were handed a new assignment by the company CEO. The assignment came out of a discussion at the meeting in which one of Regional’s clients wanted a report describing the calls being handled for them by Regional. The CEO had asked you to describe the data in a file called Regional Call Center Download Regional Call Centerand produce a report that would both graphically and numerically analyze the data. The data are for a sample of 57 calls and the following variables:
Account Number.
Past Due Amount.
Current Account Balance.
Nature of Call (Billing Question or Other).
Instructions
Summarize the case scenario of the Regional Call Center’s Washington, D.C., facility.
Develop bar charts showing the mean and median current account balance.
Construct a scatter diagram showing the current balance on the horizontal axis and the past due amount on the vertical axis.
Compute the key descriptive statistics for current and past due amounts.
Compute the coefficient of variation for current and past due account balances.
Generate analysis of the descriptive statistics, coefficient of variation, and graphs.
Recommend, based on data analysis and graphs, two strategies to improve the service to the client.
Write a 4–5 page report (including a cover page and a source list page) to the Regional clients that contain the results of the completed tasks along with a discussion of the statistics and graphs.
Provide two quality resources.
This course requires the use of Strayer Writing Standards (SWS). The library is your home for SWS assistance, including citations and formatting. Please refer to the Library site for all support. Check with your professor for any additional instructions.
The specific course learning outcome associated with this assignment is:
Apply strategies that are informed by the principles of statistical thinking and data-driven decision making to enhance business process performance.

The purpose of this assignment is to increase your knowledge of the link between social determinants of health (SDOH) and a high priority health issue with a global perspective.
Overview
Several factors come together to create an individual’s health status. The conditions in which people are born, live, work, and age can be as influential in determining an individual’s health status as the quality of diagnosis and treatment. Health care professionals need to understand the influence of these underlying conditions to deliver the best health care possible. A good example of how these factors are intertwined is the Carter Center’s work in eradicating the guinea worm in Africa and Asia. To quote from the website: When The Carter Center began leading the international campaign to eradicate Guinea worm disease in 1986, there were an estimated 3.5 million cases in at least 21 countries in Africa and Asia. Today, that number has been reduced by more than 99.99 percent. In 2020, 27* human cases of Guinea worm disease were reported worldwide. Between January 1 and June 30 of 2021 five human cases have been reported. https://www.cartercenter.org One of the major strategies used to reach this goal was teaching individuals to filter drinking water and to not go into water if infected. This was difficult for several reasons: (a) lack of health care practitioners in the largely rural area, (b) the insecurity in some areas related to conflict, and (c) cost of filtration equipment. The coordination of effort across several organizations led to the success.
The group of factors included in the SDOH are: (a) economic stability, (b) education access and quality, (c) social and community context, (d) health care access and quality, (e) neighborhood and built environment. Review the resources listed in the Instructional Materials for this module to learn more about the SDOH. Instruction
The focus of this assignment is to strengthen your understanding of the impact of at least one of the social determinants of health on a priority health issue in one of the countries listed below.
Choose from one of the following countries:
Sierra Leone
Haiti
Pakistan
Somalia
Sudan
Afghanistan
You will write a 2.5-3 page, double-spaced (~750 words) essay addressing the following:
Provide a brief description of the country you have selected. This may include information on the size of the population; median income; geography/topography; cultural and/or religious influences, etc.)
Identify one priority health issue in the chosen country. Describe the global health indicators you are using to identify the priority health issue (ie., life expectancy; maternal and infant mortality; child malnutrition, such as stunting, wasting, and underweight; infectious disease and mortality; vaccination coverage; health worker density, etc.) https://www.who.int/data/gho/data/indicators
Provide a brief description of the concept of SDOH.
Identify the SDOH that has the most impact on the identified health issue in the selected country.
Explain the link between the SDOH and the identified healthcare priority. It is possible that more than one of the SDOH categories will be applicable (you only have to include one).
Include a minimum of three (3) references. One (1) reference must be a scholarly article. References must be no more than five (5) years old. The paper will contain an introduction, a body, and a conclusion. An appropriately formatted student paper title page must be included

To make an Android app on your computer, you’ll typically follow these steps:
Set Up Development Environment: Install Android Studio, which is the official IDE for Android development. It provides all the necessary tools for building Android apps.
Create a New Project: Open Android Studio and create a new project. You’ll specify the name, package name, and other details for your app.
Design User Interface: Use Android Studio’s layout editor to design the user interface of your app. You can drag and drop UI elements and customize them as needed.
Write Code: Implement the functionality of your app by writing code in Java or Kotlin. You’ll write code to handle user interactions, perform tasks, and communicate with external services if necessary.
Test Your App: Use Android Studio’s built-in emulator or connect a physical Android device to test your app. Ensure that it works as expected and fix any bugs or issues.
Optimize and Refine: Refine your app’s design and functionality based on user feedback and testing. Optimize the performance and make any necessary improvements.
Publish Your App: Once your app is ready, you can publish it to the Google Play Store or distribute it through other channels.
Throughout this process, you’ll use Android Studio to manage your project, write code, and test your app. Additionally, you’ll need to familiarize yourself with Android development concepts and APIs to build a successful app.
