Three randomly selected households are surveyed. the numbers of people in the household are 3,4,11. assume that samples of size n=2 are randomly selected with replacement form the population of 3,4,11. listed below are the nine different samples. complete parts (a) through (c).

3, 3 3, 4 3, 11 4,3 4,4 4, 11 11, 3 11, 4 11, 11

(a) find the median of the nine samples, then summarize the sampling distribution of the median in the format of a table representing the probability distribution of the distinct median values.
(b) compare the population median to the mean of the sample medians.
(c) do the sample medians target the value of the population median? in general, do sample medians make good estimators of population medians? why or why not?
