Why is the population shape a concern when estimating a mean? What effect does sample size, n, have on the estimate of the mean? Is it possible to normalize the data when the population shape has a known skew? How would you demonstrate the central limit theorem to your classmates?
We are not here to answer your questions, but to help you answer them. However, I will give you a start. The mean acts as a fulcrum (balance point), and therefore is greatly effected by deviant scores. All other things equal, the larger the n, the more accurate the estimate of the mean.
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
