Statistics - Unbiased Estimators and Standard Error

Hi all,

Just found this question and I'm not sure how to approach it - any help is greatly appreciated smile

---
Suggest an unbiased estimator of the unknown θ and evaluate its standard error:
Z has expected value 0, variance θ and E[Z^4]=2θ²
---

Thanks
