Hello,

Can anyone guide me through how to get the moments for the mgf below:

M(s) = 4/[(3-50s)^2]

I need to know if this mgf has to be re-written as :

M(s)= E(e^{4/[(3-50s)^2]})

and then differentiated to get the moments.

OR should i just directly differentiate the M(s) = 4/[(3-50s)^2] ?

Any help would be appreciated.

Thanks
