In order to find the correlation coefficient
between two variables X and Y from 20 pairs of
observations, the following calculations were
made :
x = 15, y = %u2014 6, / xy = 50
/ x2= 61 and y2= 90.
Calculate the correlation coefficient and the slope
of the regression line of Y on X.
 
Do you have any question? or have anything to say?
