\n" );
document.write( "Hi,\r
\n" );
document.write( "\n" );
document.write( "Correct: sum of heights/# of peole = mean hieght
\n" );
document.write( "Letting x represent the number of students
\n" );
document.write( "1472in/x = 64in
\n" );
document.write( "1472/64 = x
\n" );
document.write( "23 = x the number of students measured\r
\n" );
document.write( "\n" );
document.write( "23 in this sample of students.  Hint: 23 = 11 + 1 + 11 (middle student is mean height)
\n" );
document.write( "twelve are 5ft 2 in 'or' taller and 11 are shorter then 5ft 2in  \n" );
document.write( "

\n" );
