You can put this solution on YOUR website!
σx for n = 4
\n" ); document.write( ":
\n" ); document.write( "σx = 9 / square root(4) = 4.50
\n" ); document.write( ":
\n" ); document.write( "σx for n = 16
\n" ); document.write( ":
\n" ); document.write( "σx = 9 / square root(16) = 2.25
\n" ); document.write( ":
\n" ); document.write( "σx for n = 100
\n" ); document.write( ":
\n" ); document.write( "σx = 9 / square root(100) = 0.09
\n" ); document.write( ":
\n" ); document.write( " \n" ); document.write( "
