T has a t distribution with b degrees of freedom. T2 therefore has an F distribution with 1 and b degreees of freedom. Using the formula for t distribution and transformation theory, find the density function of F=T2. You must start with the complete formula for the t distribution. Be careful as this is not a one to one transformation. Verify that the derived solution is the formula for F distrubtion in the case that a=1. This shows a relation...
