Steps to Complete Week 5 Lab

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

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

d.
How many of each
gender did you have in your study?

e.
What are other

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

d.
(Use the normal
percent of the study participants are shorter than you? What percent are taller
than you?

e.
Post a screen shot of

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

Example

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.
