Use the Weeks 3 and 5 spreadsheets from the Weeks 3 and 5 Lessons to help you answer the questions below. Step 1: Your instructor

Use the Weeks 3 and 5 spreadsheetsfrom the Weeks 3 and 5 Lessonsto help you answer the questions below.

Step 1:Your instructor will provide you with 10 values to use for this lab.

Gather 10 MORE of your own to add to the 10 provided by your instructor. Do the following:

Survey or measure 10 people to find their heights. Determine the mean and standard deviation forthe 20 valuesby 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 the20values? Is your height taller, shorter, or the same as the mean of the sample?

Data Example of 10 people with different heights

Data Example of 10 people with different heights

(your spreadsheet will have20 values10 from your instructor and 10 from your own data gathering).

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.

How did you choose the participants for your study? What was the sampling method:systematic, convenience, cluster, stratified, simple random?
What part of the country did your study take place in?
What are the age ranges of your participants?
How many of each gender did you have in your study?
What are other interesting factors about your group?
(Use theEmpirical Ruletab from the spreadsheet). Determine the 68%, 95%, and 99.7% values of the Empirical Rule in terms of the20 heightsin your height study.
What do these values tell you?
Post a screen shot of your work from the Week 5 Excel spreadsheet.
(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?
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.
