What is the percentage of athletes from Vanuatu who are taller than 175?
DIVIDE(COUNT(id where height > 175), COUNT(id)) as percentage where region_name = 'Vanuatu';
SELECT CAST(COUNT(CASE WHEN T3.height > 175 THEN 1 ELSE NULL END) AS REAL) * 100 / COUNT(T2.person_id) FROM noc_region AS T1 INNER JOIN person_region AS T2 ON T1.id = T2.region_id INNER JOIN person AS T3 ON T2.person_id = T3.id WHERE T1.region_name = 'Vanuatu'
