I tried using the for (i..) to make 1000 differents sets of numbers, but then
I dont know how to get the mean value of all of them... because I dont even
think 1000 different sets of numbers were made, because when i print it it
always shows me the same values, basically I dont know how to replicate the
funcion many times.
replicate() is your friend. Don't know why you get the same numbers
multiple times though.

Hello guys, I am stuck here:
How do I make 1000 samples of n = 10 observations from an Exponential
distribution and then compute the mean for all those 1000 samples?
Basically I need to prove the Central Limit theorem, which states:
http://www.nabble.com/file/p22664113/d175f06cbf200bd52a2c27a2e56dc594.png
Where the Sn is sum of random variables, n we have from the question, mu
is
mean and (sigma)^2 is variance.
I am having trouble setting up the function to do this.
Any help apreciated!

so little or so large that all they really do for us is puff us up and
make us feel like gods. We are mammals, and have not exhausted the
annoying little problems of being mammals.
