A population has a mean μ=73 and a standard deviation σ=24. Find the mean and standard deviation of a sampling distribution of sample means with sample size n=64.
Answer
Population mean and mean of the sampling distribution of sample means will remain same
So, mean of a sampling distribution of samples mean with size n = 64, will be equal to the population mean given in the question.
So, mean of a sampling distribution of samples mean with size n = 64 is
And standard deviation of a sampling distribution of samples mean with size n = 64, is given as
where
setting the given values, we get
So, mean and standard deviation of a sampling distribution of sample means with sample size n = 64, are 73 and 3
