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

What is the average and maximum number of hours students who made the team practiced?
SELECT AVG(T1.hs), MAX(T1.hs) FROM player AS T1 JOIN tryout AS T2 ON T1.pid = T2.pid WHERE T2.decision = 'yes'
SELECT AVG("T1"."hs"), MAX("T1"."hs") FROM "player" "T1" JOIN "tryout" "T2" ON "T1"."pid" = "T2"."pid" AND "T2"."decision" = 'yes'
