a. What is a sampling distribution?
b. How would you go about constructing a sampling distribution for the mean shoe size in the US (assume unlimited time and an unlimited budget)?
c. What would the standard error of the sampling distribution of shoe sizes tell us?
d. Explain how knowledge of such a sampling distribution and the standard error allow us to use sample data to make inferences about population parameters?
