| 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. |
I passed! I did not get a chance to tell you before the exam - but your site was excellent. I will definitely take it next year for Level II.
