Gina shape of the population distribution... vs shape of the population?
vincenthuang what's the differece between B and D
From the LOS " No matter what the shape of the orginal distribution" seems like D is close.
minna the central limit theorem does not say anything about sample size smaller than 30. So D is incorrect.
nufan It is not because it is true that it answer why statisticians use the Central Limit Theorem (..) .
amamed213 why not A ?
Jurrens it's not A bc the size of the sample is still important.
johntan1979 No, A is correct but not the answer to why statisticians use CLT.
