In two sets of variables X and Y with 50 observations each, the following data were observed. X= 10, S.D. of X=3, Y=6, S. D. of Y= 2. Coefficient of correlation between X and Y is 0.3. However, on subsequent verification it was found that one value of X (= 10) and one value of Y (= 6) were inaccurate and hence weeded out. With remaining 49 pairs of values, how is the original value of correlation coefficient affected?
