Required Resources

Read/review the following resources for this activity:

• OpenStax Textbook: Chapter 2, 6, and 7
• Lesson
• Weeks 3 and 5 Excel Spreadsheets

Scenario/Summary

This week’s lab highlights the use of probability and normal distribution.

Follow the directions below to gather data, calculate using Excel spreadsheets, and interpret the results.

Deliverables

The deliverable is a Word document with your answers to the questions posed below based on the data you find.

Required Software

• Microsoft Word
• Microsoft Excel

#### Steps to Complete Week 5 Lab

Use the Weeks 3 and 5 spreadsheets to help you answer the questions below.

Step 1: Survey or measure 10 people to find their heights. Determine
the mean and standard deviation for this group by using the Week 3 Excel
spreadsheet. Post a screen shot of the portion of the spreadsheet that
helped you determine these values. How does your height compare to the
mean (average) height of the group that you surveyed? Is your height
taller, shorter, or the same as the mean of your group? Data Example of 10 people with different heights

Step 2: Give some background information on the group of people you
used in your study. You might consider using the following questions to

1. How did you choose the participants for your study (sampling method)?
2. What part of the country did your study take place in?
3. What are the age ranges of your participants?
4. How many of each gender did you have in your study?
5. What are other interesting factors about your group?

Step 3: Use the Week 5 Excel spreadsheet for the following.

1. (Use the Empirical Rule tab from the spreadsheet).
Determine the 68%, 95%, and 99.7% values of the Empirical Rule in terms
of the ten heights in your height study.
2. What do these values tell you?
3. Post a screen shot of your work from the Week 5 Excel spreadsheet.
4. (Use the normal probability tab from the spreadsheet). Based on your
study results, what percent of the study participants are shorter than
you? What percent are taller than you?
5. Post a screen shot of your work from the Week 5 Excel spreadsheet.

Example: If my height is 73 inches, then 20.86% of the relevant population is shorter. The other 79.14%, of course, is taller.

Step 4: Be sure your name is on the Word document, save it, and then submit it under “Assignments” and “Week 5: Lab”.

This activity will be graded based on the Week 5 Lab Rubric.
