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?

  • $\begingroup$ Thank you, neerajt. Yes, it seems that 1D Expectation Maximization. I am surprised at the complexity but happy to have come across this explanation: stats.stackexchange.com/questions/72774/…. And, no Antoine, this isn't homework -- just my colorful way of describing a real world problem I am trying to solve. Thanks. $\endgroup$ – Caligator Feb 25 '16 at 15:09
