Hello (hope this is the correct place to ask)

I was wondering if some of you who are familiar with the salary ranges for QA engineers can help me out? I just graduated and the company I'm interning at wants to hire me full time. They mentioned the salary would be 45K, I'm not really sure if this is an acceptable range or not...

I didn't try to negotiate or anything since it's a first job, but I also haven't been given the official contract/document to sign yet. So, because of that, I did some research and found various ranges.. some 45K-50K, 50K-56K, etc. I'm located in California (if that helps)

Any help would be greatly appreciated!
