Edit Google Analytics code

Hello,

I would like to know where I have to go to edit the Google Analytics code.

The only thing I want is to put this snippet into the code:

setTimeout(function(){ _gaq.push([‘_trackEvent’, ‘NoBounce’, ’15 seconds’])},15000);

My ojetive is to reduce the bounce rate to thouse users who are less than 10 seconds on the page.

Please, could anybody help me??

Regards
