Transcribed Image Text:Let Y,, Y, be i.i.d with mean py and variance o.
Y is an unbiased estimator of uy.
Is
an unbiased estimator of u?
First, note that for a random variable X
var(X) = E(x°) - E(X? = E(x)- and E(XX) =, for itj.
%3D
So,
in
E(Y) =t
j=1 j#i
Hence,
O A.
Yes,
is an unbiased estimator of u
O B.
No,
is not an unbiased estimator of u.
Y is a consistent estimator of µy. Is Y a consistent estimator of u?
