Example 18 - Yola

In two sets of variables X and Y with 50 observations each the following data were observed. = 10, = 6, σx = 3, σx = 2 Coefficient of correlation between X and Y is 0.3. However on subsequent verification it was found that one pair (X = 10, Y = 6) was inaccurate and hence waived out. ................
