The mean of a normal probability distribution is 615; the standard deviation is 17.
\n" ); document.write( "
\n" ); document.write( "(a) About 68% of the observations lie between what two values?
\n" ); document.write( "

Between 615-17 and 615+17 which is between 598 and 632

\n" ); document.write( "B) About 95% of the observations lie between what two values?
\n" ); document.write( "

Between 615-2(17) and 615+2(17) which is between 581 and 649

\n" ); document.write( "c) Practically all of the observations lie between what two values?
\n" ); document.write( "

Between 615-3(17) and 615+3(17) which is between 564 and 666\r\n" );
