## chi

To prove that the distribution with n degrees of freedom is a gamma distribution with and , do i just do:

the cumulative distribution function of :

instead of the normal

and find the cumulative distribution function and then the density function? does that work, or am i making things up again?

I don't know what you have to do to get full marks, but if you know the density of the and the Gamma distributions and can show that with particular (valid) parameters they have the same densities then you have shown that they are in such circumstances the same distribution.

(the acceptability of such a demonstration depends on how your course has defined the distributions and if you know their denstities and how having the same distribution has been defined)
