\n" ); document.write( "If you have 11% of the general population being left handed, you'd assume 11% of the class was left handed.
\n" ); document.write( "You can only choose an integer number of left handed desks.
\n" ); document.write( "3 desks would mean 3/30 or 10% are left handed.
\n" ); document.write( "4 desks would mean 4/30 or 13.3% are left handed.
\n" ); document.write( "Choosing four seems adequate since it gives you a little extra room above the 11% whereas 3 desks leaves you shy of the average 11%.
\n" ); document.write( "So yes, adequate.
