Researchers A and B each have a random sample from the same
population, which has mean and a finite variance. Here are their
data:
Researcher A
Researcher B
Sample sizes
nA
nB
Sample means
Consider the following claims:
Claim 1. If nA > nB, the
estimator puts too much weight on researcher A’s
observations to be efficient.
Claim 2. If nA ≠≠ nB, the
estimator is biased.
Claim 3. If nA > nB, we can make the
estimator more efficient by...
