I want to know the answer to the following question:
How many Norfolk Island residents voted on May 8, 2015?
All the background I'm provided with is that "On 8 May 2015, voters were asked if Norfolk Islanders should freely determine their political status and their economic, social and cultural development, and to "be consulted at referendum or plebiscite on the future model of governance for Norfolk Island before such changes are acted upon by the Australian parliament".". Is that enough to answer the question?
Answer: no
