Jun 1 accepted Which of two quantities is greater? May 30 comment Which of two quantities is greater? Thanks @Michael. For the comparison of these functions, (say $f$ and $g$), I can simply show $f(0)=g(0)$, the slope of $g$ is more negative than that of $f$ and that $g$ is decreasing throughout $(0,1)$. Is that right or is there a more compact way of doing this? May 30 comment Which of two quantities is greater? Hi. I have a follow-up question: I need to show $(x-y)^{((x-y)/(2x-y))}\times (x+y)^{((x)/(2x-y))}>x$. I am not sure how the AM-GM inequality leads to this, as the GM is on the LHS? May 29 asked Which of two quantities is greater? May 21 comment Computing expectation of a function of two random variables @zoli: Yes, there are $N-1$ independent draws and the $N^{th}$ is dependent on the previous draws. Your understanding is right. May 21 comment Computing expectation of a function of two random variables @zoli: Why not? I never said within array $X$, the draws are independent. $x_n(\omega)=S_x-\sum_{i=1}^{N-1}x_i$ for all $\omega$.
