Thank professor for the reply. I found my current answer is quite close to a similar post last year (i.e., g_hat = 1.42. I pasted that post below). But I could not access to the suggested link for the discussion (

http://book.caltech.edu/bookforum/showthread.php?t=424). Does anyone know what causes this solution?

Thanks.
