Unless there is something I'm missing, there doesn't seem to be a question here. They tell you the distribution of theta. You know the mean and variance of a gamma; solve for the usual parameters.

Consider parameters such that and

You are told solve for

The pdf will then be - Feb 3rd 2011, 07:57 PMholly123
is that really all there is to it?

That's what I read.

The whole 'prior' thing made it sounds bigger than what it was. But everything described was prior so it all links together easily.
