\n" ); document.write( "Hi,
\n" ); document.write( "you did not say what method You use to translate z-value to P-value
\n" ); document.write( " μ = 1518 , σ = 325
\n" ); document.write( "one SAT is randomly selected:
\n" ); document.write( "P(x>1600) = 1 - P(\"z+=+%281600-1518%29%2F325\")
\n" ); document.write( " 64 SAT scores are randomly selected:
\n" ); document.write( "P( x >16000) = 1 - P( \"z+=+%281600-1518%29%2F%28325%2F8%29\" ) \n" ); document.write( "
\n" );
