I assume there would be a better/smarter way, but I was not in the mood so I copied something similar from a few lines above and adapted it slightly:
<pre>
$('#accepts-advertising-set-yes').live('click', function(e) {
e.preventDefault();
var $this = $(this);
var $block = $('.block.accepts_advertising');
$block.find('input[type="radio"][value="t"]').prop('checked',true);
$block.find('input[id*=accepts_advertising_no][value="f"]').prop('checked',true);
} );
</pre>
