For a given set of 25 items, coeff‌icient of correlation between x and y is 0.6. The values of the arithmetic mean of x and y are 14 and 18, respectively, and the values of standard deviation of x and y are 4 and 6. respectively. If the pair (25. 18) has been wrongly taken as (18, 25). then find the correct value of correlation coeff‌icient.
