[r] Is there a significant correlation between x and y? (yes or no) [sign] Calculate the value of the coefficient of determination (round to three decimal places). [r-sq] Find the equation of the least-squares regression line (round each coefficient to three decimal places). y = [a] + [b]x Predict the number of entry-level jobs for a neighborhood with 4000 total jobs (round to the same number of decimal places as y).
