 (a) Find the equation of the least-squares regression line with response variable sodium

 content and input variable fat content.

 (b) Compute the SSE (sum of squares of errors) for the least-squares regression line. 


(c) The line y = 160 + 8x is near but not equal to the least-squares regression line that you

 found above. Compute the SSE for this line and note how your answer compares with the answer in part (b).
