Google Analytics "unexpected T_String

I’m actually not entirely sure what version of wordpress I’m using, as I’m editing it from a different computer to the one that it is installed on, and I can’t access the admin at all right now. Basically, I updated a whole load of plugins that looked pretty out of date. One of them was google analytics, and as soon as it said it had successfully updated I went somewhere else in the admin site and was met with just this message, in red:

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or ‘}’ in /usr/local/pem/vhosts/263636/webspace/siteapps/137538/htdocs/wp-content/plugins/google-analytics-for-wordpress/wp-gdata/wp-gdata.php on line 14

The code it is talking about is this:

<script type="text/javascript">//<![CDATA[
	// Google Analytics for WordPress by Yoast v4.2.3 | http://yoast.com/wordpress/google-analytics/
	var _gaq = _gaq || [];
	_gaq.push(['_setAccount','UA-23884067-1']);
	_gaq.push(['_trackPageview']);
	(function() {
		var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
		ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
		var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
	})();
	//]]></script>

I have very limited programming knowledge, and so really don’t know what has happened. But it seems plausible that it has been hacked? Also, I didn’t set up the website or install any of the plugins, I’m just updating it for someone else, so I don’t know what was on there in the first place that could have resulted in this. Any suggestions would be much appreciated
