Checkbox is not showing checked even though the value is 1 from the database

I have a checkbox . It is always shown unchecked even though its value is 1. Can anyone help me with the jquery syntax for this.

<td>
  <div>
   <label for="Active">Active</label>
  </div>
 <div class="checker" >
   <input id="Z_ACTIVE" type="checkbox" />
</div>
</td>
