According to Chebyshev's theorm at least 84% lies between what two numbers.
\n" ); document.write( "I understand the theorm is supposed to be 2.5 Standard deviations but I don't see how that number is reached using the Formula. I get caught on the Algebra when the numbers are simplified to the point of
\n" ); document.write( "1-(1/K^2) = 0.84
\n" ); document.write( "1/k^2 = .16
\n" ); document.write( "k^2 = 1/0.16
\n" ); document.write( "k = 1/0.4
\n" ); document.write( "k = 2.5\r
