The apparently automatic scholarships for stats would give $12k for the OP’s 1380 SAT score, assuming GPA >= 3.0: https://finaid.olemiss.edu/scholarships/#8 . But University of Mississippi’s out-of-state list price is around $36k, according to https://finaid.olemiss.edu/cost-of-attendance-2019-2020/ , so the OP would need additional competitive scholarships or other money to make it affordable.
The OP’s SAT score converts to a 30 ACT, which, if GPA >= 3.0, gets a full tuition scholarship at University of Southern Mississippi: https://www.usm.edu/undergraduate-scholarships/freshman-scholarships.php . However, the deadline was 12/1, and non-tuition costs appear to be about $15-16k, according to https://www.usm.edu/financial-aid/cost-attendance.php .
