|
|
n
|

|
N

|
(n-1)

Explanation:
Detailed explanation-1: -The central limit theorem says that the sampling distribution of the mean will always be normally distributed, as long as the sample size is large enough. Regardless of whether the population has a normal, Poisson, binomial, or any other distribution, the sampling distribution of the mean will be normal.
Detailed explanation-2: -When a variable in a population is normally distributed, the sampling distribution of for all possible samples of size n is also normally distributed. distribution is N(, /√n).
Detailed explanation-3: -The sample mean symbol is x̄, pronounced “x bar”. The sample mean is an average value found in a sample.
