Sxx Calculate the intercept, a= - bx, and interpret its meaning as it pertains to this problem. The least-squares linear regression equation is = a + bx = Once a regression line has been found, the coefficient of determination provides a measure of how well the line describes the data. Calculate the coefficient of determination, R. Does the line fit the data well? (circle one) Very Good Good ("A") ("B") Satisfactory Poor ("C") Bad ("D") ("F") STAT 008 AFlores 09.21
