For an IQ test, we know the population � 5 100 and the �X 5 16. We are interested
in creating the sampling distribution when N 5 64. (a) What does that sampling
distribution of means show? (b) What is the shape of the distribution of IQ
means and the mean of the distribution? (c) Calculate �X for this distribution.
(d) What is your answer in part (c) called, and what does it indicate? (e) What is
the relative frequency of sample means above 101.5?
