Hi,

I want to know if mean of A>B and A1, A2 are the two subsets of A. Similarily, B1, B2 are two subsets of B. Is the condition A1<B1 and A2<B2 mathematically possible?????

As I think it is not. I think that either both or at least one subset must have shown the same relationship in their average values as that of whole data set A and B.

It would be really helpful, if anyone can help me on this..
