You will complete 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

1. 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.
2. Please complete the provided worksheet.
   • Project Part I Worksheet(Links 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.
  • Create 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
