You are currently working at NCLEX Memorial Hospital in the Infectious Diseases Unit. Over the past few days, you have noticed an increase in patients admitted with a particular infectious disease. You believe that the ages of these patients play a critical role in the method used to treat the patients. You decide to speak to your manager and together you work to use statistical analysis to look more closely at the ages of these patients. You do some research and put together a spreadsheet of the data that contains the following information:

Client number

Infection Disease Status

Age of the patient

You need the preliminary findings immediately so that you can start treating these patients. So let’s get to work!!!!

Background information on the Data:

The data set consists of 60 patients that have the infectious disease with ages ranging from 35 years of age to 76 years of age for NCLEX Memorial Hospital. Remember this assignment will be completed over the duration of the course.

5. What is the P-value? Explain how you determined it.

6. What is the critical value? Explain how you calulated it.

7. What is your decision? Reject the null or do not reject the null? Explain why you made your decision including the results for your p-value and the critical value.

8. State the final conclusion in non-technical terms.

Please show your work for the construction of the test-statistic and explain your process for finding the p-value and critical value. You may use the Equation Editor to format your calculation steps on the Word document or attach an Excel spreadsheet clearly showing each calculation for #B4 and #B5, but your answers still need to appear on the Word document.

Why might you want to create a report using R Markdown?

R Markdown has better spell-checking tools than other word processors.

R Markdown allows you to automatically add figures to the final document.

R Markdown final reports have smaller file sizes than Word documents.

R Markdown documents look identical to the final report. incorrect

Answer

Incorrect:

Try again. The final report looks different than the working R Markdown document. For example, plots called in the R Markdown document do not show up until the final report is compiled.

You have a vector of student heights called heights. You want to generate a histogram of these heights in a final report, but you don’t want the code to show up in the final report. You want to name the R chunk “histogram” so that you can easily find the chunk later.

Which of the following R chunks does everything you want it to do?

```{r, histogram, message=FALSE}

hist(heights)

```

incorrect

```{r histogram, warning=FALSE}

hist(heights)

```

```{r, echo=FALSE}

hist(heights)

```

```{r histogram, echo=FALSE}

hist(heights)

```

Answer

Incorrect:

Try again. message=FALSE and the similar warning=FALSE stop R from printing non-code text, but the code will still be echoed.

n <- nrow(mtcars)

```

Here `r n` cars are compared

What will be the output for the above Rmarkdown file?

The only output is the text: Here 32 cars are compared.

Since we have echo=F, the code chunk is not evaluated, therefore we will have both the code and the text: Here `r n` cars are compared. incorrect

The code will be displayed as well as Here 32 cars are compared.

R cannot comprehend the value of n, we will get an error.

Part A                                                                                                                     

You are working as an accountant for Bronson, Lazenby & Dalton and the senior partner has asked you to prepare a report answering the following questions about consolidation procedures for a client:

Follyfoot Ltd has a 33% interest in the share capital of Cue Ltd, which is a company involved in the same industry as Follyfoot Ltd. The remaining share capital is owned by Mr and Mrs Lewelyn who are the founders of Cue Ltd. Mr and Mrs Lewelyn have given Follyfoot Ltd three out of five seats available on the board of directors. Follyfoot Ltd takes the lead on all decisions but the business is closely monitored by Mr and Mrs Lewelyn who hold the other two board positions.

Advise the directors of Follyfoot Ltd of the requirements of AASB 10 in respect of the control criterion and how they would apply to this investment.

Why is it necessary to make adjustments for intra-group transactions?

As the majority of the directors do not have an accounting background, your report answering the questions must be written to convey a clear understanding of consolidation accounting concepts (control vs significant influence) and other relevant accounting issues.

Homework 06: Iteration
Overview: Examine PyCharm’s “Introduction to Python” samples for Loops. Use PyCharm to work along with a worked exercise from Chapter 5. Use two different looping strategies for different purposes.
Prior Task Completion:
1. Read Chapter 05.
2. View Chapter 05’s video notes.
3. As you view the video, work along with each code sample in PyCharm using the Ch 5 Iteration PPT Code Samples.zip.
Important: Do not skip the process of following along with the videos. It is a very important part of the learning process!
Specifics: PyCharm’s “Introduction to Python” project contains several examples of iterations or looping (see list at right). Follow the instructions to complete them. (Not handed in.)
Use PyCharm to work along with the video solution for Exercise 5.1 from the textbook. Type in the statements and execute the program as is done in the video. [Create a project and save your work as “Worked_Exercise_5.1”. It will prove valuable for part a below.] (Not handed in.)
Create a new PyCharm project called “Hwk06_”. Create two new python files within that project called “Hwk06a_” and “Hwk06b_”.
Part (a): Let’s write the code to prompt the user for (an integer) blood-sugar reading (BSR) and print a warning message if it is over 500. Also, print the message “>> Invalid input” if the user enters a non-integer, such as a float or a string.
Having completed Worked_Exercise_5.1 above you should use that code as the basis for this problem.
Use this sample interaction to demonstrate your code:
Enter a BSR: 155
Enter a BSR: string input
>> Invalid input
Enter a BSR: 522
** Warning! Blood sugar reading over 500: 522
Enter a BSR: 485
Enter a BSR: 578
** Warning! Blood sugar reading over 500: 578
Enter a BSR: 210
Enter a BSR: 330.6
>> Invalid input
Enter a BSR: 519
** Warning! Blood sugar reading over 500: 519
Part (b)
Create a list of BSRs as follows:
blood_sugar_readings = [155, 190, 522, 485, 578, 210, 130, 519]
Use a for-loop to iterate through the list in order to find the highest and lowest BSR values. Note that finding the maximum and minimum values of a list using a for-loop is shown in Section 5.7.2 of the textbook on p. 62-3. (Note that since we are ‘hard-coding’ the list, we may assume the data is valid, i.e., it has been previously checked.)
HINT: as is done in the textbook, while developing the code, add a print statement as the last line of the for-loop writing out the current BSR value, the smallest, and the largest. Then when your code is running correctly, you can comment out that line (but leave it in the code-base).
After looping through the list, print the highest and lowest BSR values.
What to hand in:
Take screen snips of the Run window for Parts (a) and (b). Use the snipping tool on the console portion of the screen – but including the header bar and the file name.
Copy the snips into a Word document (filename Hwk06_YourLastName_ScreenSnips.doc) with your name and date in the upper right hand corner.
Upload the Word doc and the Python program files Hwk06a_YourLastName.py and Hwk06b_YourLastName.py to the appropriate assignment in the LMS. Three files total.
NOTE: As was described in the previous assignment, each Python file you create should be documented with (minimally) the following three lines at the top of each file:
# Filename: Hwk06_YourLastName.py
# Author:    < your name>
# Date Created: 2017/09/05
# Purpose: < brief descriptions>

Read the following article

The Mayo Clinic and the technology company Medically Home are partnering to launch a new healthcare delivery model that will deliver “advanced care” typically available inside a hospital into patient homes.

Financial terms of the partnership announced Wednesday weren’t disclosed but executives involved said Boston-based Medically Home is providing “technology infrastructure.” And Mayo, which made an undisclosed investment in Medically Home last year, is providing the medical care or directing those that do provide the treatment for “high acuity patients.”

“Under the direction of Mayo Clinic physicians, advanced care at home offers comprehensive and restorative health care services including infusions, skilled nursing, medications, laboratory and imaging services, behavioral health, and rehabilitation services from a network of paramedics, nurses and an ecosystem of support team members,” Mayo said in a statement.

The first such programs to offer “advanced care at home” will be implemented in July in Jacksonville, Fla., and in August in Eau Claire, Wis. Mayo has long had hospitals, health facilities and physicians in those markets.

The partnership comes as medical care providers escalate their efforts to use the latest technology to center treatment around the patient, making sure healthcare is delivered in the right place, at the right time and in the right amount. Some also see the effort to provide more healthcare into patient homes as ready to take off as cases of the coronavirus strain Covid-19 continue their surge and patients look for new safe and effective ways to get home-based care during the pandemic.

“Offering comprehensive, acute and restorative level care to patients in the comfort and safety of the home is an expectation of patients,” Mayo Clinic Platform president Dr. John Halamka said in a statement accompanying the announcement. “Advances in technology and platform business models allow us to give patients the next generation of medical care and experience consumers expect. It is a shifting paradigm in the health care system and Mayo Clinic intends to lead this new option for patients.”

Medically Home has already been attracting investments for its projects like its “Virtual Hospital,” which the company says “transforms patients’ homes into temporary hospital units, enabling advanced medical care at bedside.” Last year, the big healthcare supplier and distributor Cardinal Health invested $10 million into Medically Home.

Mayo said it selected Medically Home as a partner because the platform allows medical care providers to “shift advanced medical care to patients’ homes safely” and offers “an integrated technology platform and network of in-home services” that can be director by Mayo doctors. “The work we will be doing together in this model will have a profound impact on how we all look at the future of medical care,” Medically Home executive chairman Raphael Rakowski said.
