Question 758046: a.) A population has a normal distribution. A sample of size 94 is selected from this population. Describe the shape of the sampling distribution of the sample mean?
b.) A population has a normal distribution. A sample of size 11 is selected from this population. Describe the shape of the sampling distribution of the sample mean

a.) A population has a normal distribution. A sample of size 94 is selected from this population. Describe the shape of the sampling distribution of the sample mean?
The Central Limit Theorem says:
The mean of the sample means is the mean of the population.
The std of the sample means is (population std)/sqrt(94)
=====================================================================
b.) A population has a normal distribution. A sample of size 11 is selected from this population. Describe the shape of the sampling distribution of the sample mean
Ans: mean of sample means = u
std of sample means = (sigma)/sqrt(11)
============================================
