I got a question on estimation theory. Can anyone explain it to me or give me a link with some tut and solutions so I can get a better understanding. I got a maths question which i have asked for help but no one has replied yet. Since it was a statistical question I should have posted it here. The question can be found here: https://www.physicsforums.com/showthread.php?t=401521 I'm stuck on part (b) The two issue I think I have with the question are that I don't understand the term "binomial proportion" and estimation theory in general. Can and one explain this to me?
