Week 5 Lab Assignment Name: Tavia Thompson Instructor Name: Professor Andrew Please use this template to help answer the questions listed in the lab instructions. The “steps” below refer to the steps listed in the lab instructions. Type your answers and post your screenshots in the spaces given below. Then, save this document with your name and submit it inside the course room. Step 1. Gather Data Your instructors will post 10 data values to use for this lab. The data values represent the HEIGHTS of 10 people. Please reach out to your instructor if you did not receive the assigned 10 data values for the term by Monday of Week 5. ( NOTE: This is NOT the data used in the lab video, which is about midterm grades. Do not use the midterm grades data.) 1a. 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. (Round statistics to two decimals.) Mean Height in Inches 66.85 Sample Standard Deviation in inches 4.74 Your Height in Inches 64 1

1b. Post a screenshot in the space BELOW of the portion of the spreadsheet that helped you determine these values. Please list the 10 heights your professor provided first followed by the 10 heights you collected. There should be 20 values to determine the mean and sample standard deviation. Data (inches): 60,62,64 , 66 , 68 , 68 , 68 , 69 , 70 , 73 , 75 , 60 , 62 , 70 , 72 , 58 , 72 , 67 , 69 , 64 1c. Answer the following two questions (Answer in complete sentences). 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? 2

My height (64 inches) is less than the mean (66.85) of the data collected. This indicates that I am shorter than the average height of the sample. Step 2. Data Characteristics Answer the following questions to give some background information on the group of people you used in your study. Write in complete sentences. 1. How did you choose the participants for your study? What was the sampling method: systematic, convenience, cluster, stratified, simple random? The height data was collected by convenience sampling. This was accomplished by asking my coworkers and patients at work because this method was easiest for me to access. 2. What part of the country did your study take place in? My study took place in Texas, which is the South-Central part of the U.S. 3. What are the age ranges of your participants? The age ranges of the participants in my study were 29-60 years old. 4. How many of each gender did you have in your study? In my study, there were 13 women and 7 men that participated. 5. What are other interesting factors about your group? 3

The participants in my study come from diverse cultural backgrounds and different economic classes. Step 3. Data Analysis Answer the following questions. Use the Week 5 Excel spreadsheets to help analyze the data. Empirical Rule 1. Determine the 68%, 95%, and 99.7% values of the Empirical Rule in terms of the 20 heights in your height study. (Use the Empirical Rule tab from the spreadsheet). 68% 62.1119 71.5881 95% 57.3738 76.3262 99.70% 52.6357 81.0643 2. What do these values tell you? Write complete sentences explaining what the values in the Empirical Rule tell you in context of the data. According to the values, there is a 68% chance that the mean of the heights will be between 62.11 and 71.59 inches. There is a 95% chance that the average height will be between 57.37 and 76.33 inches. Finally, there is a 99.70% chance that the mean height will be between 52.64 and 81.06 inches. 4

3. Take a Screenshot of your Empirical Rule Sheet (Week 5 Spreadsheet) and provide it below Normal Distribution 1. Take a Screenshot of your Normal Distribution Sheet and provide it below 2. Based on your study results, what percent of the study participants are shorter than you? What percent are taller? Based on the study results, 27.35% of the participants are shorter than me and 72.65% are taller than me. 5
