A computational formula for the sample variance is:
\n" ); document.write( "A: S2 = s*n
\n" ); document.write( "B: S2 = [∑X2-(∑X)2]/N
\n" ); document.write( "C: S=√(S2)
\n" ); document.write( "D: µ=S/N
\n" ); document.write( "E: none of the above
\n" ); document.write( "--------------------
\n" ); document.write( "Ans: B
\n" ); document.write( "
\n" );
