if the confidence level is 87%, that means the alpha = 1 minus .87 = .13.
\n" ); document.write( "alpha / 2 is therefore equal to .065.
\n" ); document.write( "the critical z-score will therefore be plus or minus 1.514101887.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this can be seen in the following displays using the z-score calculator that can be found at https://davidmlane.com/hyperstat/z_table.html\r
