In order to find the correlation coefficient between two variables X

In order to find the correlation coefficient between two variables X and Y from 12 pairs of observations, the following calculations were made: 2x = 30, y = 5, 2x = 670, y2 = 285 and 2xy = 334, on subsequent verification it was found that the pair (x = 11, y = 4) was copied wrongly, the correct value being (x = 10, y = 14). Find the correct value of correlation coefficient. =
