Refer to the U. S. population (USPOP) data in Appendix C. Construct a two-stage cluster sampling estimate of the total population in the United States for 2010 by first sampling divisions and then sampling states within divisions. Sample four of the nine divisions and at least two states within each sampled division. Compute an estimate of the variance attached to your estimator. Would you recommend this procedure over stratified random sampling

play black ops 4 answer a

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
