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
