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, 0.444 and 0.888:\r\n" );

document.write( "\"%280.444%2B0.888%29%2F2+=+0.666\"\r\n" );
document.write( "\r\n" );
document.write( "So p̂ = 0.666\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( "E = |0.888-0.666| = |0.444-0.666| = 0.222\r\n" );
