With respect to the thread located here:
For the following data calculate sampling distribution parameters.
m=80, sigma=10, s=8, n=25 for E[M] and SE[M]
is this a mean question?? Apparently they want an answer in general and sample mode right?
Will you explain further or rather provide another example, this time when the standard deviation is not known?So you have \(\displaystyle \mu = 80, \sigma = 10, s=8, n=25\)
Then \(\displaystyle E(X) = \mu\) and \(\displaystyle SE = \frac{\sigma}{\sqrt{n}}\)
