Three randomly selected households are surveyed. The numbers of people in the households are 1, 4 and 10. Assume that the samples of size n=2 are randomly selected with replacement from the population of 1, 4 and 10. Listed below are the nine different samples:
1,1 1,4 1,10 4,1 4,4 4,10 10,1 10,4 10,10
Find the variance of each of the nine samples: (find s^2 and probability)
s^2 is 4.5, 0, or 1? Whats the probability?
s^2 is 9, 4.5, 2.3? Whats the probability?
s^2 is 18, 72, or 9? Whats the probability?
s^2 is 20.3, 81 or 40.5? Whats the probability?
