\n" );
document.write( "On an exam with a mean of M=82, you obtain a score of X=86  
\n" );
document.write( "a. Would you prefer a standard deviation of s=2 or s=10?  s = 2
\n" );
document.write( "   z = 4/2 = 2  OR z= 4/10 = .4
\n" );
document.write( "b. If your score were X=78, would you prefer s=2 or s=10?  s = 10
\n" );
document.write( "  z =  -4/2 = -2  OR z = -4/10 = -.4
\n" );
document.write( "c. If one scores below the mean, one wants the SD to be larger. 
\n" );
document.write( "If one scores above the mean , one would wish the SD to be smaller. 
\n" );
document.write( "That is: it will reflect a better position as to placement on the curve.
\n" );
document.write( "
\n" );
document.write( "   \n" );
