Question

: A researcher collected the following information for two variables x and y No. of pairs = 20, r = 0.5, mean of X is 15, mean of Y is 20, standard deviation of X is 4, standard deviation of Y is 5. Later on it was found that one pair of value as been wrongly taken as (X = 16, Y = 30) whereas the correct values were (X = 26, Y = 35). Find the correct value of r, solution.
