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?

  1. We do not do your work for you. Consult your textbook.

    However, I will give you a little help.

    Of the three measures of central tendency, the mean is most effected by deviant scores.

    Look at the formula for confidence interval of a mean to determine the effect of n.
