   Hi,
   
   in this question i get as far as e^beta=sumy/n ie e^beta=ybar
   the solution says that
   beta=ybar
   but why do we not take logs as the beta is in the exponential
   i thought it was beta=lnybar
   
   can someone help please?
   thank you

   Hi Alfie
   It should be beta=ln ybar, it is correct in the ASET but not in the examiners report, it was a typo
   Thanks Andrea
