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 for the 20 values 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 20 values? Is your height taller, shorter, or the same as the mean of the sample? 4 A 7 I 7 c7 0 . a 7 r 1J_l r 1 'MmhmmMMWhmn 2 3 y ' 4 m 5 u a .

Data Example of 10 people with different heights (your spreadsheet will have 20 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. 1. How did you choose the participants for your study? What was the sampling method: systematic, convenience, cluster, stratified, simple random? 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. 39. (Use the Empirical Rule tab from the spreadsheet). Determine the 68%, 95%. and 99.7% values of the Empirical Rule in terms of the 20 heights in your height study. 30. What do these values tell you? 31. Post a screen shot of your work from the Week 5 Excel spreadsheet. Empirical Rule 68-95-99.7 mean 74.3 Lower number Upper number standard deviation 1.6 68% 61.3 87.3 95% 48.3 100.3 99.70% 35.3 113.3 Week 5 Spreadsheet Example b. (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? c. 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.

The spreadsheet is an MS office 365 file, I am not certain if it's backward compatible with earlier office versions (it should be) and if you can open it with an apple devide. I am attaching the values directly below for those of you that have difficulties opening the file. Heights (in) 58 59 60 60 60 65 66 67 69 72
