For a set of 10 pairs of values of x and y, the regression line of x on y is x 0; mean and standard deviation of y being 8 and 2 respectively. Later it is known that a pair (x = 3, y = 8) was wrongly recorded and the correct pair detected is (x = 8, y = 3). Find the correct %3D regression line of x on y.
