Question 287575: consider an infinite population with a mean of 160 and standard deviation of 25,a random sample size of 64 is taken from this population. the standard deviation of the sample mean equals? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! consider an infinite population with a mean of 160 and standard deviation of 25,a random sample size of 64 is taken from this population. the standard deviation of the sample mean equals?
------------
std of means of sample of size 64 = 25/sqrt(160) = 1.9764...
