Question

Which of the following variables or variable expressions completes the following sentence under the Central Limit Theorem: The distribution of the sample mean is normal, with mean represented by the parameter µ and standard deviation represented by the parameter:

Select one:

$s/%u221An$√n

$\sigma /$√n

Answer 1

Correct option:

$\sigma /\sqrt{n}$

EXPLANATION:

By Central Limit Theorem, the sampling distribution of the sample mean is Normal Distribution with mean = $\mu$ = mean of the population and standard deviation = $\sigma /\sqrt{n}$ , where $\sigma$ is the standard deviation of the population.
