1. measure your own height and arm span (from finger-tip to finger-tip) in inches. you will likely need some from a parent, guardian, or sibling to get accurate measurements. record your measurements on the "data record" document. use the "data record" to you complete part two of this project.2. measure five additional people, and record their arm spans and heights in inches.3. share the names and measurements of the people you measured, as well as your own measurements, with your student partner in the class. together, you and your partner will have 12 sets of data. (you may request a method of getting a partner from your teacher.)name relationship to student arm span in inches height in inchesryan me 64 64paige girlfriend 63 68paul little sibling 48 48niyah little sibling 48 47emery infant sibling 34 33owen friend 62 45part two: representation of data with plots1. using graphing software of your choice, create a scatter plot of your data. predict the line of best fit, and sketch it on your graph.2. copy and paste your scatter plot into a word processing document.3. share and discuss your scatter plot and predicted line of best fit with your partner. if your scatter plots or lines of best fit are different, discuss reasons why they might be different. part three: the line of best fitinclude your scatter plot and the answers to the following questions in your word processing document.1. which variable did you plot on the x-axis, and which variable did you plot on the y-axis? explain why you assigned the variables in that way: because u can find the height of people(y) by plugging arm span in x. and i can find people's arm span(x) by plugging height as y2. write the equation of the line of best fit using the slope-intercept formula y=mx+b. show all your work, including the points used to determine the slope and how the equation was determined.3. what does the slope of the line represent within the context of your graph? what does the y-intercept repr esent? 4. test the residuals of two other points to determine how well the line of best fit models the data.5. use the line of best fit to you to describe the data correlation.6. using the line of best fit that you found in part three, question 2, approximate how tall is a person whose arm span is 66 inches? 7. according to your line of best fit, what is the arm span of a 74-inch-tall person? .
