Question 1136572: 1) A population has a mean of μ = 50 and a standard deviation of σ= 12.
For samples of size n = 16, what is
the mean (expected value) and
the standard deviation (standard error) for the distribution of sample means?
I found the standard deviation (standard error) = 3
but for the mean would it just be 50?
Thank you in advance.

i believe so.
standard error = 12 / sqrt(16) = 12 / 4 = 3.
the average of all sample means is expected to be the population mean.
here's a reference.
