Two pair misread values. A computer while calculating she correlation coefficient.between two variables x and y obtained the following constants: N=25, Ex=125, Ex²=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 coefficient between x and y.
