Hi,
you did not say what method You use to translate z-value to P-value
 &#956; = 1518 ,    &#963; = 325
one SAT is randomly selected:
P(x>1600) = 1 -  P({{{z = (1600-1518)/325}}})
  64 SAT scores are randomly selected:
P( <span style="text-decoration: overline">x</span> >16000) =  1 - P( {{{z = (1600-1518)/(325/8)}}} )
