I have the following: the expected value and the variance of a PDF.
I am running 3 simulations with n=10,n=20, and n=30.
I need the population standard deviation of the mean of a sample size n from your distribution
I thought it would be just the square root of the (variance/n), is that not correct? (so thus 3 different sd's.
Or is it simply the square root of the variance?
Further on I am asked to find the table of the proportion of means within one and two stadard deviations of E(X), and I use the following code:
which would mean the sqrt(var/n) is the standard deviation, correct?
