Math Problem Statement
The "Central Limit Theorem will tell us a few important things:
-
The mean of ALL sampling distributions equals the mean of the populaiton.
-
The standard deviation for a sampling distribution is equal to where is the population standard deviation.
-
For n 30 or larger the sampling distribution should be approximately normal.
If Population mean = 24.4
Population standard deviation = 6.49
sample size n = 37
The MEAN of the sampling distribution = ________
Solution
Based on the Central Limit Theorem, the mean of the sampling distribution is equal to the mean of the population.
Given the information:
- Population mean () = 24.4
- Sample size () = 37
The mean of the sampling distribution is:
Answer:
The mean of the sampling distribution = 24.4

Here are five related questions to expand your understanding:
- What is the formula for the standard error of the mean in a sampling distribution?
- How does increasing the sample size affect the standard error of the mean?
- What happens to the shape of the sampling distribution if the sample size is less than 30?
- Why does the Central Limit Theorem assume that the sampling distribution becomes approximately normal for ?
- How can the Central Limit Theorem be used to make inferences about the population from the sample?
Tip: The larger your sample size, the closer the sampling distribution of the mean will approximate a normal distribution, even if the population itself is not normally distributed.
