Well observed. Your question shows your insight. Yes, this is a bit tricky. My colleague, Magnus Levin at Linnaeus Uni, did his PhD on this and other collective nouns. There is an argument for both 'percentage' and 'population' to be the head. eg. percent could be equates with some as in 'Some students passed the test', then clearly 'students' would be the head. For my part, as regards testing ... I have accepted both as being ok as it is ambiguous.
