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.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
