3.4. For the MU284 population, the coefficient of variation of the variable CS82 equals 0.543. Determine the minimum (expected) sample size needed to esti- mate the total of CS82 so that the relative standard error of the n estimator, [V(r)]^2/t, is no greater than 10% under (a) simple random sampling (SI) and (b) Bernoulli sampling (BE). (C) What is the expected sample size required under Bernoulli sampling, i the alternative estimator (3.2.6) is used instead of the n estimator? 3.4.
