On a particular examination paper, a pupil whose mean score is {see attachment} will actually score X, where X has a {see attachment} distribution. Over the pupils taking the test, {see attachment} is assumed to have a {see attachment} distribution. Find the density of the test score of a randomly chosen pupil.

Given that Fred has scored x, what is the distribution of his underlying mean score?

Suppose {Xi : i =1,2.....n} are independent, with Xi having the Exponential Distribution...
