Question

select the correct answer.

as the number of samples increases, which value can be used to approximate a population mean?

the standard error of the mean
the mean of the sample means
the confidence interval
the standard deviation

Explanation:

Analyze the behavior of sample means

$$ \mu_{\bar{x}} = \mu $$

Apply the Central Limit Theorem

$$ \lim_{N \to \infty} \bar{X}_N = \mu $$

Answer:

• the standard error of the mean
• the mean of the sample means (Correct answer)
• the confidence interval
• the standard deviation
