When using sample means as estimators,we usually estimate the population standard deviation with
A)the sample standard deviation.
B)the sampling distribution standard deviation.
C)the population parameter.
D)the Z score.

When using sample means as estimators, the best way to estimate the population standard deviation is by using the sample standard deviation. This is because the sample standard deviation is based on the data from the sample and provides a good estimate of the variation within the population. The other options (B, C, and D) are not appropriate because the sampling distribution standard deviation relates to the distribution of sample means, the population parameter is what we are trying to estimate, and Z score is used for calculating probabilities and making statistical inferences, not for estimating standard deviation.
