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?

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 guide your answer.
a. How did you choose the participants for
your study (sampling method)?
b. What part of the country did your study
take place in?
c. What are the age ranges of your
participants?
d. How many of each gender did you have in
your study?
e. What are other interesting factors about
your group?
Step 3: Use the Week 5 Excel spreadsheet for the following.
a. (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.
b. What do these values tell you?
c. Post a screen shot of your work from the
Week 5 Excel spreadsheet.

5 Spreadsheet Example
d. (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?
e. 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”.
