CREATE TABLE table_8679 ("Position" FLOAT, "Club" CLOB, "Played" FLOAT, "Points" FLOAT, "Wins" FLOAT, "Draws" FLOAT, "Losses" FLOAT, "Goals for" FLOAT, "Goals against" FLOAT, "Goal Difference" FLOAT)

When the goals against were higher than 30, what was the average number of draws?
SELECT AVG("Draws") FROM table_8679 WHERE "Goals against" > '30'
SELECT AVG("Draws") FROM "table_8679" WHERE "Goals against" > '30'
