Read the Architecture Connection. The table lists the amount of lean, measured in millimeters, for thirteen different years.

a. Make a scatter plot of the data. Let x represent the year, and let y represent the amount of lean in millimeters.
b. Find a median-median line for the data.
c. What is the slope of the median-median line? Interpret the slope in the context of the problem.
d. Find the amount of lean predicted by your equation for 1992 (the year work was started to secure the foundation).
e. Find the root mean square error of the median-median line. What does this error tell you about your answer to 8d?
f. What are the domain and range for your linear model? Give an explanation for the numbers you chose.
