Question: A computer while calculating carrelation coefficient between two variables X and Y from 25 pairs of observations obtained the following results : n = 25, X 125,  2X 650,  Y1 0 0 ,  2Y 460,  XY 508. Later it was discovered that the values (X, Y) = (8, 12) was copied as (6, 14) and the value (8, 6) was copied as (6, 8). Obtain the correct value of the correlation coefficient.
