Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE lives_in ( stuid VARCHAR, dormid VARCHAR )
TABLE: CREATE TABLE student ( age INTEGER, stuid VARCHAR )
TABLE: CREATE TABLE dorm ( dorm_name VARCHAR, dormid VARCHAR )

### Question ###
Find the average age of students living in each dorm and the name of dorm.

### Accurate SQL ###

SELECT AVG(T1.age), T3.dorm_name FROM student AS T1 JOIN lives_in AS T2 ON T1.stuid = T2.stuid JOIN dorm AS T3 ON T3.dormid = T2.dormid GROUP BY T3.dorm_name
