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
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.

Week 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”.
