Answer #1

a) P(-1 < t < 1) = P(T < 1) - P(T < -1)

                      = 0.8347 - 0.1653

                     = 0.6694

Graph:

b) P(T > C) = 0.01   where C = 6.965

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...
