Thank you for the video, can you help me how to prove that is unbiased in this question? Question: Compare the average height of employees in Google with the average height in the United States, do you think it is an unbiased estimate? If not, how to prove it is not mathced?

No problem. Glad this was helpful!

very clear explanation

[@kipngenopozee]

Are those parameters constant?

[@mathadamspiegler6463]

Yes, parameters (theta) are constant. We use an estimator (which is variable due to the randomness in sampling) to estimate the fixed value of the parameter.
