Question

Calculate the covariance of the following data:
X - 4,5,6,7,8,9,10,11,12,13,14,15
Y - 78,72,66,60,54,48,42,36,30,24,18,12​

Answer 1

Answer:

4,5,6,7,8,9,10,11,12,13,14,15

Y - 78,72,66,60,54,48,42,36,30,24,18,12

Answer 2

answer X = 16 , Y = 6

X series = +1 +1 +1 +1.....

Y series = 6+6+6+6+.......
