Determine the level of the confidence given the confidence coefficient z(α/2) for the following situation:
\n" ); document.write( "z(α/2) = 2.58
\n" ); document.write( "------
\n" ); document.write( "Right tail = normalcdf(2.58,100) = 0.0049
\n" ); document.write( "---
\n" ); document.write( "2*0.0049 = 0.0099
\n" ); document.write( "-----
\n" ); document.write( "Rounding get 0.01 or 1% in the 2 tails.
\n" ); document.write( "----
\n" ); document.write( "Level of confidence = 99%
\n" ); document.write( "=================================
