You will do a Course Project in this course that will span two weeks. The project is broken into two parts. You will complete Part I in Week 6 and Part II in Week 7. In Week 6, Confidence Intervals will be explored and in Week 7 Hypothesis testing will be explored.
A confidence interval is a defined range of values such that there is a specified probability that the value of a parameter lies within the interval.
In Part I of this project, you will analyze data, complete research and provide a write-up that includes calculations.
Deliverables
- Your professor will provide you with 50 pieces of data. Email your professor at the beginning of Week 6 if you did not receive the 50 pieces of data for Course Project Part I.
- Please complete the provided worksheet.
- Project Part I WorksheetLinks to an external site.
- Introduction--Provide a description of the data you were provided and discuss what you know about the chosen topic.
- Sample DataProvide the 50 data values on your worksheet. You must provide ALL of your sample data.
- Problem ComputationsFor the topic, you must answer the following:
- Determine the mean and standard deviation of your sample.
- Find the 80%, 95%, and 99% confidence intervals.
- Make sure to list the margin of error for the 80%, 95%, and 99% confidence interval.
- make your own confidence interval (you cannot use 80%, 95%, and 99%) and make sure to show your work. Make sure to list the margin of error.
- Provide a sentence for each confidence interval created which explains what the confidence interval means in context of topic of your project.
- Problem AnalysisWrite a half-page reflection.
- What trend do you see takes place to the confidence interval as the confidence level rises? Explain mathematically why that takes place.
- Explain how Part I of the project has helped you understand confidence intervals better?
- How did this project help you understand statistics better?

Introduction
(REMOVE THIS LINE PRIOR TO SUBMITTING REPORT: Summarize what you have learned about confidence intervals from the articles above. Discuss why it would be important to find the population mean of the data used for this term.Provide a description of the data you were provided and discuss what you know about the chosen topic.)
Sample Data
(REMOVE THIS LINE PRIOR TO SUBMITTING REPORT: List ALL of the sample data in the table below.)
Directions:
- Use the table above to create an 80%, 95%, and 99% confidence interval.
- Choose another confidence level (besides 80%, 95% or 99%) to create another confidence interval.
- Provide a sentence for each confidence interval created above which explains what the confidence interval means in context of topic of your project.
Computations
(Round the mean and sample standard deviation to values to FIVE decimal places)
(REMOVE THIS LINE PRIOR TO SUBMITTING REPORT: Calculate each of the following.)
Sample Mean =
Sample Standard Deviation =
(Round the lower/upper limits and margin of error to THREE decimal places).
