problem 3:

a) Define SRS:

• With replacement
• Without replacement from a finite population.

b) In srswor obtain the variance of the estimate of the population proportion.

problem 5:

a) Describe systematic sampling. Obtain the variance of the estimated mean.

b) What do you mean by cluster sampling? Find out the optimum cluster size for fixed cost.

problem 6:

a) Describe the concept of circular systematic sampling. Obtain the variance of the estimated mean in clusters of equivalent sizes.

b) If the population comprises of linear trend then prove that stratified random sampling is more efficient as compared to systematic and simple random sampling.
