Adult Northern and Southern Yeti heights can each be represented as normal distributions: Yeti Type mean sd Northern 92in 4.5in Southern 95in 4.2in

20,000 Yeti adults attend a concert, each one’s height being recorded upon entry.

What could one say about the proportion of Northern vs Southern Yeti at the concert based only on the 20K height measurements?
