(a) What practical problems arise in establishing a frame, such as a map or list of units, from which to select the sample?

(b) How is the sample selection actually carried out?

(d) Estimate the population mean or total using ratio estimation.

(e) Estimate the variance of the estimator above.

(f) Give a 95% confidence interval for the population mean or total.

(g) How would you improve the survey procedure if you were to do it again?
