comment Averages of mixed random variables
There is nothing stated on the problem about independence but I believe unless it is explicitly stated we are allowed to assume they are independent.

Got it! Thank you. Answer seems to be $n/2(a_1 + a_{n})$

comment Closed form solution of a definite integral?
It's been a while since doing IBP, for the second one I ended up getting $-e^{-x}\(x^2 - 2x) - 2$, does that seem correct?

Nevermind, I see where you said it is a 'fancy way of asking to compute the integrals'. Thank you! This was very helpful.

comment Closed form solution of a definite integral?
So are you saying I should be using integration by parts for both, or just the second? I'm not really sure what a closed form solution is aside from what I've been able to read up on it by searching online.
