It's concerning full credibility and partial credibility.
Page 77 question C14, and C15 deal with the same type of problem.
My question is why do they use the following equation for the full
credibility:
Nf=(y/k)^2
and they assume that sigma over m the coefficient of variation in
both question is zero. For this to be true then P(Xi=d)=1 has to be
true, but I don't think it is. Could it be a mistake? I just want to
make sure.
Thanks
