jQuery not running in WordPress

jQuery not running in WordPress

I see to get a strange problem in my website which is yogihosting.com. The problem is that jQuery is not running in it. Everything is correct and i have checked them multiple times. Even an alert is not running.

However the code runs when i place it in a simple html file. My website is in WordPress i think that is is some WordPress feature which is not letting it to run. The code is -

  1.  <script type="text/javascript" src="JS/jquery-2.1.1.js"></script>
     <script type="text/javascript">
            $(document).ready(function () {
                alert('hi');
            });
        </script>
