Why is population shape of concern when estimating a mean? What does sample size have to do with it?
----------------------------
The central limit theorem applies to populations that are normaly distributed,
i.e. have a bell-shaped distribution look.
You take a sample and draw a conclusion about the population mean based
on the central limit theorem.
-------------------------------
As the sample size increases sqrt(n) increases to s/sqrt(n) becomes
smaller and you get a better estimate of the population mean.
