CREATE TABLE table_19154 ("High School" TEXT, "Type" TEXT, "Established" FLOAT, "Enrollment" FLOAT, "Mascot" TEXT, "WIAA Classification" TEXT, "Notes" TEXT)

What is the lowest enrollment value out of the enrollment values I'd the schools with a 3A WIAA clarification?
SELECT MIN("Enrollment") FROM table_19154 WHERE "WIAA Classification" = '3A'
SELECT MIN("Enrollment") FROM "table_19154" WHERE "WIAA Classification" = '3A'
