Dear all,

Please could you help me with the following.

I am trying to solve a problem in which it is asked to compute Covariance(X,Y).

The information the problem gives are:

sum Xi = 859; sum Xi^2 = 47 387
sum Yi = 1 095; sum Yi^2 = 78 737
sum XiYi = 60 262; n = 18; i = 1, ...n

COV(X,Y) = ?

Many thanks!
