Question

HELP PLEASE ASAP!
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.

2. 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 represent?
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 help 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?

My plot:

68 inches 65 inches
68 inches 67 inches
64 inches 64 inches
36 inches 37 inches
61 inches 64 inches
69 inches 70 inches
65 inches 66 inches
70 inches 69 inches
62 inches 61 inches
71 inches 70 inches
64 inches 65 inches
70 inches 72 inches
