Express the confidence interval
\n" ); document.write( "42.9% < p < 60.3% in the form of
\n" ); document.write( "ˆ
\n" ); document.write( "p̂±E.
\n" ); document.write( "

\r\n" );
document.write( "A confidence interval always has p̂ in the exact middle of the interval.\r\n" );
document.write( "\r\n" );
document.write( "To find the middle, average the lower and upper bounds, 42.9% and 60.3%:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So p̂ = 51.6%\r\n" );
document.write( "\r\n" );
document.write( "The value of E is the difference in absolute value between p̂ and either\r\n" );
document.write( "bound. \r\n" );
document.write( "\r\n" );
document.write( "E = |42.9%-51.6%| = |60.3%-51.6%| = 8.7%\r\n" );
document.write( "\r\n" );
document.write( "so \r\n" );
document.write( "\r\n" );
document.write( "p̂±E = 51.6% ± 8.7%\r\n" );
document.write( "\r\n" );
