Sampling distributions and the Central Limit Theorem

Question 1

Unbiased estimator for mean

Answer 1

The mean of the sample means is equal to the population mean

Myu_(x bar) = Myu

Question 2

Unbiased estimators

Answer 2

Myu_(x bar) = Myu

Myu_(p hat) = proportion aka p

Question 3

Unbiased estimator for proportion

Answer 3

Sample proportion (p hat) must equal the true for population proportion (p)
