Overview
- Project Part 5: 90% Confidence Interval for the Population Mean
- 1) Using the 35 values you created for Project Part 1, you will find the 90% Confidence Interval.
- If you did not collect the 35 values yet, review the TemplateDownload Template and the Data Sets for Project Part and the Semester Project page, collect them now.
- 2) Ensure your data is in L1, and then use the Student's t-Distribution.
- Stat > Tests > Line 8 TInterval > Data > List: L1, Freq: 1, C-Level: 0.90 Calculate.
- 3) Using at least 2 quality sentences answer the following:
- What is your confidence interval?
- What can you say about the population mean of your chosen data set? Be sure to relate this to the Level of Confidence. (Include your data title in your description.)
- Why do you have to use the Student's t-Distribution?
When working on each part of the Semester Project the Best Practice is to type the information onto the appropriate slide of the TemplateDownload Template, removing the directions, and then copy and paste your work and results into the text submission area of the assignment.
You may submit the project part as a text submission, Word Document, or the PowerPoint Slide from the Template (only that slide!) Do not submit your work as an embedded image in one of those files. Images cannot be accepted for these assignments. (File Types allowed: .doc,.docx,ppt,.pptx)
