Three randomly selected households are surveyed. the numbers of people in the household are 4,5, and 9. Assume that sample of size n=2 are randomly selected with replacement from the population of 4,5 and 9. Listed below are the nine different samples:4,4; 4,5; 4,9; 5,4; 5,5; 5,9; 9,4; 9,5; 9,9find the variance of each of the nine samples, then summarize the sampling distribution of the variances in a table representing the probability distribution of the sample variances.
