Please use this template to help answer the questions listed in the lab instructions. The “steps” below refer to the steps listed in the lab instructions. Type your answers and post your screenshots in the spaces given.
- Write a paragraph summarizing what you learned from the articles provided. Consider the use of confidence intervals in health sciences with these articles as inspiration and insights.
Data Collection
Use the data set you collected for the Week 5 lab (heights of 10 different people plus the 10 heights provided by your instructor). (NOTE: This is NOT the data used in the lab video, which is about midterm grades. Do not use the midterm grades data.)

Summarize the Preliminary Calculations (Round to 2 decimal places):
Please answer the following questions in complete sentences:
- Discuss your method of collection for the values that you are using in your study (systematic, convenience, cluster, stratified, simple random).
- What are some faults with this type of data collection?
- What other types of data collection could you have used, and how might this have affected your study?
Calculation of 95% Confidence Interval
- Give a point estimate (mean) for the average height of all people at the place where you work. What is your point estimate, and what does this mean?
Solution
Write a paragraph summarizing what you learned from the articles provided.
Based on the articles provided, confidence interval (CI) is one of the most important tools in health sciences that allow estimating the range within which it is expected that a true population parameter will reside when using a sample. A CI offers a spread of possible values of a population parameter, and a 95% CI, perhaps the most popular among scholars, conveys that out of many samples taken, 95% of calculated intervals will cover the actual value…
