Hi Kelya,
I'm not in your field so I can't give you specific advice, but generally I think you have to know yourself to see where you would be competitive. Are you a top 10 school student? Is your resume competitive enough to be among the top 10% of applicants to a top 10 school? Admissions committees often look at stuff like your GPA, research experience, publications (if you have any), your SOP and recommendation letters and your GREs. A good strategy when applying I think is to apply to a couple schools that you think are at your level, apply to 1 or 2 that are 'reach' schools - schools that you would love to get into but you're not sure you're competitive at, and to 1 or 2 that you think you have a very good shot at getting accepted at, but may not the most prestigious reputation.
Ultimately the strength of your resume/profile will determine where you're competitive at, but applying to a good mix of schools is probably the best strategy. Hope this helps!
