Analytics Code Installation for HOSTED solution

I am using a hosted version of WordPress and wanted to install Analytics. Doing Google Webmaster tools was easy enough. Seeing a previous thread they said to go to Admin/Appearance/Editor and then modify footer.php….

That’s great except when I go to Appearance there’s no ‘editor’ sub menu and none of the sub menus there seem to bring me to an editable file of any sort much less footer.php

It has Themes, Widgets, Menus, Theme Options, Background, Custom Design, Mobile, iPad

Any advice would be appreciated, thanks….
