Let T=

Find the mean and variance of T.

some other info: are iid rv with density function , x>=0 and h>0, h is an unknown variable

I'm not really sure how to approach this problem

Any help will be appreciated

Thanks in advance

Obtain the mean and variance of any particular ln(1+x):

Define

I haven't checked but those integrals look do-able to me.

Then,Use the standard results for summing independant variables

I got

from wolfram

are you supposed to use wolfram to do your integrals?

anyway, for the last step you are expected to notice that all the are iid, so
