Three randomly selected households are surveyed. The numbers of people in the households are 4, 5, and 9. Assume that samples of size n = 2 are randomly selected with replacement from the population of 4, 5, and 9. Listed below are the nine different samples. Complete parts (a) through (c).
4,4 | 4,5 | 4,9 | 5,4 | 5,5 | 5,9 | 9,4 | 9,5 | 9,9

(a) Find the median of each of the ninesamples, then summarize the sampling distribution of the medians 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?

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."
