Help with Unbiased Estimators

1. The problem statement, all variables and given/known data

See attached.

2. Relevant equations

3. The attempt at a solution

I have no issues with part A. I simply took the expected value of T1 and T2 and everything turned out fine. What I'm having issues with is part B.

I have:
T1 = (4 / n) * 1997 - 2 = 0.08075
T2 = (4 / n) * 32 = 0.03334

Why are my answers so different if they are both unbiased estimators? Shouldn't they at least be somewhat close to each other?

Your answers are correct. The expected value of T1 is θ. However, any observed value of T1 may or may not be close to θ.
