Sorry the first one i formatted poorly, and couldn't figure it out. New to this forum, just figuring stuff out.

Homework Statement You have i.i.d. random variables X1,...,Xn ~ Normal (\Theta,c^2*\Theta^2), where "c" is a known positive constant (relative variability = std. dev(X)/E[X]) and \Theta is an unknown positive constant. Find the first four moments. E.g E[Xj] where j=1,2,3,4. Homework...
