Using a correlated sub-query, display course name, course number and the average capacity of all sections of each course, rounded to 4 decimal places, where students are enrolled, and the average capacity is less than 25. Use a column alias of AVERAGE_CAPACITY to represent the number. (16 rows)

What will be an ideal response?

```
SELECT description, c.course_no, ROUND(AVG(capacity), 4)
AVERAGE_CAPACITY
FROM section s, course c
WHERE c.course_no = s.course_no
AND EXISTS (SELECT null
FROM enrollment e
WHERE e.section_id=s.section_id)
GROUP BY description, c.course_no
HAVING ROUND(AVG(capacity), 4) < 25
```
