*checksum 708**checksum 106.2*Use your calculator to make a scatterplot and graph the least squares regression line (LSRL). Sketch the graph and LSRL on your paper. Remember to put a scale on the

*x*-axis and*y*-axis of your sketch. Write the equation of the LSRL rounded to four decimal places.With your calculator, find the residuals as you did in part (c) of problem 6‑33. Make a table with the

*distance from wall (inches)*as the first column, and*residual (inches)*in the second column. What is the sum of the squares of the residuals?

See scatterplot below. *y* = 1.6568 + 0.1336*x*

See table below.

Use your calculator to find the sum of the squares of the residuals.
