\n" );
document.write( "Hi
\n" );
document.write( "For the normal distribution: 
\n" );
document.write( "one  standard deviation from the mean accounts for about 68% of the set 
\n" );
document.write( "two standard deviations from the mean account for about 95%
\n" );
document.write( "and three standard deviations from the mean account for about 99.7%.
\n" );
document.write( "mean of a normal probability distribution is 716; the standard deviation is 11.
\n" );
document.write( " (a) About 68% of the observations lie between what two values? 705 and 727
\n" );
document.write( " (b) About 95% of the observations lie between what two values? 694  and 738
\n" );
document.write( " (c) Practically all of the observations lie between what two values? 683 and 749\r
\n" );
document.write( "\n" );
document.write( " \n" );
document.write( "

\n" );
