Then in your two follow up posts, respond at least once in each option. Use the discussion topic as a place to ask questions, speculate about answers, and share insights.
Be sure to embed and cite your references for any supporting images. Write a confidence interval problem using one of the options below. For whichever option you choose, gather the appropriate data and post your problem (without a solution) in the discussion topic. Allow time for your classmates to post their solutions, and then respond to your own post with the solution for others to check their work. Option 1: Think about a population mean that you may be interested in and propose a confidence interval problem for this parameter.
Your data values should be approximately normal. For example, you may want to estimate the population mean number of times that adults go out for dinner each week. Your data could be that you spoke with seven people you know and found that they went out 2, 0, 1, 5, 0, 2, and 3 times last week. You then would choose to calculate a 95% (or another level) confidence interval for the population mean. Assume a random sample was chosen, which is required to determine a confidence interval.
Option 2: Think about a population proportion that you may be interested in and propose a confidence interval problem for this parameter. For example, you may like to estimate the population proportion of adults in the US who own SUVs. The data could be that you researched online by looking at a local dealership to find that 142 of the 432 vehicles sold are SUVs. You want to calculate a 90% (or another level) confidence interval for the population proportion. Assume a random sample.

IV Type: Normal Saline
Location: Room 302, General - Medical Unit

Date: October 20, 2023
Student Name: [Your Name]
Assigned vSim: J.D. in simulated environment
Reason for Hospitalization
J.D. is hospitalized due to an acute exacerbation of chronic obstructive pulmonary disease (COPD) characterized by worsening dyspnea, wheezing, and cough. He has a long-standing history of smoking and has received outpatient management, but recent events—such as a respiratory infection—have exacerbated his condition, necessitating inpatient care.
Health History/Comorbidities
J.D. has a health history notable for chronic obstructive pulmonary disease, hypertension, and hyperlipidemia. His COPD has been attributed to several decades of smoking, and he expresses awareness about needing to quit. His hypertension is managed through medication, and he follows a dietary regimen for hyperlipidemia.
Shift Goals and Patient Education Needs
1. Patient Education on COPD Management: Educate J.D. on recognizing exacerbating symptoms and the importance of adhering to his medication.
2. Smoking Cessation Resources: Provide resources to support quitting smoking, emphasizing how it correlates with improved lung function and overall quality of life.
3. Understanding Medication Regimens: Help J.D. comprehend the use and side effects of prescribed medications, including bronchodilators and corticosteroids.
4. Nutritional Guidance: Connect him with a nutritionist to discuss dietary changes that may help optimize his health, considering his COPD and other comorbidities.
Pathways
Path to Discharge: The patient will be discharged when he demonstrates stable respiratory status, effective use of inhalers, and understanding of self-management, particularly around smoking cessation and medication adherence.
Path to Death or Injury: Potential risks for J.D. include respiratory failure, exacerbation leading to hospitalization due to non-adherence to therapies, or complications associated with his comorbid conditions.

Confidence Interval Problem - Option 1
For this assignment, I've chosen Option 1 to explore a confidence interval problem with a focus on population mean.
Problem Statement
Let’s consider a hypothetical scenario where we are interested in estimating the average number of hospital visits per year for patients diagnosed with COPD. The data collected from a random sample of 10 patients with COPD has yielded the following number of hospital visits in the past year: 5, 3, 6, 2, 4, 8, 1, 0, 7, and 2.
Using this sample data, we will calculate a 95% confidence interval for the true mean number of hospital visits per year for COPD patients in this population.
Data
- Sample: 10 patients
- Observations: 5, 3, 6, 2, 4, 8, 1, 0, 7, 2
Objectives for Calculations
1. Calculate the sample mean.
2. Calculate the sample standard deviation.
3. Determine the standard error.
4. Find the critical value for a 95% confidence level.
5. Construct the confidence interval.
