CREATE TABLE college (cname CLOB, state CLOB, enr NUMBER)
CREATE TABLE player (pid NUMBER, pname CLOB, ycard CLOB, hs NUMBER)
CREATE TABLE tryout (pid NUMBER, cname CLOB, ppos CLOB, decision CLOB)

What is the average number of hours spent practicing for students who got rejected?
SELECT AVG(T1.hs) FROM player AS T1 JOIN tryout AS T2 ON T1.pid = T2.pid WHERE T2.decision = 'no'
SELECT AVG("T1"."hs") FROM "player" "T1" JOIN "tryout" "T2" ON "T1"."pid" = "T2"."pid" AND "T2"."decision" = 'no'
