    Q8. Part I
    I got confused on seeing the question based on buhlman straub credibility theory.
    I am unable to link it with clarity, how this question refers to buhlman straub credibility model. Could some one help - why E(var(theta)) is taken as 0.2 whereas var(Xi) used to derive other value ? Apologies for inconvenience , here is original question and solution.
