the correlation coefficient between two variables x and y obtained the folfowing constants: N=25, Ex=125, Ex-650, Ey-100, Ey=460, Exy=508. It was however later discovered at the time of checking that he had copied down two pairs of observations as (6, 14), (8, 6) while the correct values were (8, 12), (6, 8). Obtain the correct value of the correlation çoefficient between x and y.
