Answer:

The explanation is given below.

Explanation:

When we study the data retailing to two variables X and Y, we obtain a measure of the correlation coefficient between X and Y.
The correlation coefficient is obtained as
r =#[#Cov(x,y)#/(sigma_x#.#sigma_y)#]
Here #Cov(x,y)# signifies the variation between X and Y
#sigma_x# is a measure of the standard-deviation within the values of X.
#sigma_y# is the measure of the standard deviation of values within Y.
