Just suppose we wake up tomorroe morning and discover, shock horror, that some eminant scientist has finally proved evoultion to be imposible and untrue. What would we do with all those millions of incorrect text books and TV documentuaries?
You never know this could happen, after all evoulton is far from from being proved true. So who knows...

I understand that the expected value of the mean of a random variable equals the "true" mean of the variable, but how do you show that with rules of expectations? I also need to show the same thing for the variance of x-bar equals (sigma^2 / n).

Prove: If A, B, C are sets, then (A-B) X C = (AXC) - (BXC), where "A-B" is the set containing all elements of A that are not in B, and AXC denotes the Cartesian product between A and C. Obviously, to prove this, one must show that for any ordered pair (x,y), if it is contained in the set on the left side of the equation, it is necessarily in the one on the right, and vice versa. The proof seems almost obvious. I just want someone to write down a set of logical steps showing how they arrive at the above statement.
