Hi all, I'm planing to apply for PhD. in statistics for Fall 2019. I need a few suggestions regarding the schools I'm applying. Undergraduate: non US university GPA 3.26/4.00 (Major:Statistics with research experience) Graduate: currently doing a Master of Applied Statistics, GPA 4.00/4.00 GRE 307(160-Q and 147-V) I haven't taken TOEFL since most of the schools waived the TOEFL requirement if you have a degree from US university. Recommendation: from 3 professors who I know well . I'm planing to apply for some universities ranking from 20-50 (US news ranking). Do you think is it reasonable to apply to theses ranked universities or should I lower my expectation? Thank you
