UC Davis and UC Irvine are not safeties. I am not sure about Rutgers.
Two things about universities in Canada. One is that admissions is largely stats based, and your stats are pretty good. The other is that at least Toronto and UBC are very large, particularly compared to the population of Canada. McGill is large at least compared to the English speaking (Anglophone) population of Quebec. This means that admissions at the top universities in Canada tends to be a lot more likely compared to admissions at the top universities in the USA. There are also a lot of very good universities in Canada. There are a lot more than just the few most famous ones that are very much worth considering. Toronto and McGill are known for grade deflation, but are very good universities where you can get a very good education. Plan to work hard if you get into either of them.
There are a few of us here on CC who are somewhat familiar with universities in Canada (eg I am originally from Montreal) so if you want to tell us where you are applying we can make suggestions.
Given that you are interested in anthropology, it might be worth mentioning that there is a very good museum of anthropology at UBC in Vancouver BC. If you ever make it to Vancouver then you should definitely take the time to visit the museum.
I do not know what WU is. WUSTL is Washington University in St Louis. Is this what you mean? I am assuming that USC is Southern California, because South Carolina would be closer to a safety.
I do not think that you need to double major. You can major in statistics, or in mathematics, and just take the anthropology classes that are interesting to you. If you take a full load of anthropology classes, and if you subsequently decide to do so, then a graduate degree in anthropology would still be possible. Math and statistics are however easier fields to help you get a job after graduating.
Your grades will be interpreted in the context of the high school where you are studying. Do you have any sense regarding where this puts you in terms of rank? Is there any chance that you are the top student in your high school? In most public high schools in the US an unweighted 3.85 GPA might or might not put you in the top 10%. However, universities seem to be able to both find out what grade scales are typical for your high school, and interpret your grades in that context.
If NYU is your top choice, and if you are sure that you can afford it for a full 4 years, then I think that it is worth applying ED. It is hard to predict what your chances would be, and they might depend as @SJ2727 suggested on how well you can explain what sort of interdisciplinary degree you want and why. To me statistics is something that combines well with a variety of social sciences including anthropology, so it seems at least plausible that you might indeed have a good idea why you want to do this.
And your TOEFL of 111 might be the highest that I have seen, and suggests that your English is at least as good as the average American or Anglophone Canadian. This part at least will not be a problem at all.
Best wishes.
