Answer:
D.The standard deviation of all sample means is the population standard deviation divided by the square root of the sample size.
Explanation:
The central limit theorem is a fundamental probability and statistics theorem. This theorem states that the mean data distribution of a population sample that has a specific purpose will approach a normal distribution as the sample size increases, so the entire sample distribution means that x bar will go as the sample size increase, will approach a normal distribution. With this, we can say that the average of all sample means is the average of the mu population.
This theorem is very useful when it is necessary to analyze factors related to the theory of statistical inferences.
