At time t= 0, 11 identical components are tested. The lifetime distribution of each is exponential with parameter À. The experimenter then leaves the test facility unmonitored. On his return 24 hours later, the experimenter immediately terminates the test after noticing that y = 5 of the 11 components are still in operation (so 6 have failed). Derive the mle of A. [Hint: Let Y = the number that survive 24 hours. Then Y Bin(n, p). What is the mle of p? Now notice that p = P(X, 2 24), where X, is exponentially distributed. This relates i to p, so the former can be estimated once the latter has been.) (Round your answer to four decimal places.)

What do you think is the best way of sorting out these type of questions. When I'm studying I somehow always mix up negative and positive values or get something off somehow. so that I get one part wrong which leads to getting another part wrong and so on. I understand the concept of elimination and subsition but I can't seem to carry it out very well.

Can i share my screen and show you a homework problem that I thought I did right but is wrong and I don't know what I've done wrong?

it says your answers are wrong

It is the same question
