Health care administration leaders face many challenges when executing decision

/in /by

Health care administration leaders face many challenges when executing decision making for day-to-day operations in their organizations. For example, consider how organization-wide initiatives, such as promoting patient and employee safety, represent overarching guidelines that a health care administration leader must ensure are thoroughly enforced. 
How might health care administration leaders determine what is best for their organization? What types of considerations might health care administrators take into account when enforcing organizational guidelines and practices?
For this Assignment, review the resources for this week and the “Case Study Assignment” document. Reflect on the issues presented in the Case Study assigned and consider how you might approach the case as a health care administration leader.
Individual Case Study Analysis (1–2 pages):
Create an individual Case Study Analysis that includes: 
A summary of the facts associated with the case, including the primary leaders
A description of skills and traits of the primary leaders in this case

You must find at least one internet source about a recent (post 2014) development in nanotechnology and also answer the following questions.

What do medicinal chemists do and where do they work?

Why isn’t preventing cancer a priority in drug development?

What are some of the drugs to watch in 2016? What diseases do this drugs target? (Additional reading attached)

Who is the “Drugs to watch” report written for?

What are some problems with drug development?

What are drug company R&D divisions doing to overhaul current models?

What are some risks to drug companies doing R&D?

Please answer the questions for 280-350 words. That means the answer does not need to be specifically overall. Thank you for your help.

Question description

In this project you will produce a statistical analysis of our unique class data on SVSU students. You choose which variables that you want to study. It would be interesting to focus on one group of variables (for example, “recreation”) but you can choose variables from separate categories if you want.

The paper should be structured in 5 parts. The first part is an introduction. Here you want to describe the purpose of the paper and what kind of data you will be using. In describing the data, briefly discuss how the questions were designed and how the surveys were collected. Mention possible shortcomings of this survey.

In the second part, statistically describe the data. Choose at least 3 variables, and make sure you have at least one numerical and two categorical variables. For two categorical variables, show a contingency table. For the numerical variable, give summary statistics, including mean, median, mode, variance, and standard deviation (show these in a table).

In the third part, visualize the data. Show a bar chart or a pareto chart for one categorical variable and a histogram for a numerical variable. I recommend doing these in Excel, using the first Excel lab as a guide.

In the fourth part, formulate and test a hypothesis about a variable. The best type of hypothesis will have some sort of research involved- i.e., can you find any info online about the age of SVSU students that you could test using our data? How about the percent of students who are married? Number of classes they are taking? State the null and alternative hypothesis, calculate the test statistic, compare it to a critical value, and state your conclusion.

In the fifth part, write a brief conclusion about your analysis. What did you learn? What were the difficulties you faced? How would you improve this study in the future?
