For the n=4 states selected in Exercise 8.29, record their 2000 population sizes from Appendix C. Use these data to estimate the total population aged 65 and over in the northeastern states and place a bound on the error of estimation. Is the actual total included in your interval estimate? Do you think this method of sampling is better than selecting a simple random sample of four states for purposes of estimating total population? Why?
Exercise 8.29
Refer to the U.S. population figures given in USPOP in Appendix C. From the nine northeastern states, select a sample of four states with probabilities proportional to their total population sizes in 2000. Is this procedure an appropriate sampling scheme for estimating total unemployment in the Northeast? Is this procedure an appropriate sampling scheme for estimating acres of forestland in the Northeast?
