II. 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, an subsequent verification it was found that one pair (X = 10, Y = 6) was inaccurate and hence weeded out. With the remaining 49 pairs of values, how is the original value of correlation coefficient affected?
