\n" ); document.write( "Remaining area:: 1-0.69 = 0.31
\n" ); document.write( "-----
\n" ); document.write( "Left-tail:: 0.31/2 = 0.155
\n" ); document.write( "-----
\n" ); document.write( "z-value border for that left tail:: invNorm(0.155) = -1.0152
\n" ); document.write( "z-value border for the right tail:: 1.0152
