If those were server loads for just your site with one user on it, then I would be concerned. However, since you are on a shared server, those loads are going to include other sites on the server. I'm not sure how accurate they are for the whole server, as Jason pointed out, but I do know they are not for ONLY your site.
As Jason also asked, how is your site running? If it's running fine, I wouldn't worry about those numbers.
