	j)	(a) The following are the number of departmental stores in 10 cities: 35, 27, 24, 32, 42, 30, 34, 40, 29 and 38. If we want to select a sample of 15 stores using cities as clusters and selecting within clusters proportional to size, how many stores from each city should be chosen? (Use a starting point of 4). (b)What sampling design might be used to estimate the weight of a group of men and women?
	k)	Suppose that we want a sample of size n = 30 to be drawn from a population of size N = 8000 which is divided into three strata of size N1 = 4000, N2 = 2400 and N3 = 1600.How should a sample of size n = 30 be allocated to the three strata, if we want optimum allocation using sampling design.
	l)	A certain population is divided into five strata so that N1 = 2000, N2 = 2000, N3 = 1800, N4 = 1700, and N5 = 2500. Respective standard deviations are: s1 = 1.6, s2 = 2.0, s3 = 4.4, s4 = 4.8, s5 = 6.0 and further the expected sampling cost in the first two strata is Tk. 4 per interview and in the remaining three strata the sampling cost is Tk. 6 per interview. How should a sample of size n = 226 be allocated to five strata if we adopt proportionate sampling design; if we adopt disproportionate sampling design considering (i)                 only the differences in stratum variability (ii)               Differences in stratum variability as well as the differences in stratum sampling costs.
	m)	A population is divided into three strata so that N1 = 4000, N2 = 2500 and N3 = 2800. Respective standard deviations are: s1 = 12, s2 = 17 and s3 = 4. How should a sample of size n = 75 be allocated to the three strata, if we want optimum allocation using disproportionate sampling design?
	n)	A population is divided into three strata so that N1 = 5000, N2 = 2000 and N3 = 3000. Respective standard deviations are: s1 = 15, s2 = 18 and s3 = 5. How should a sample of size n = 84 be allocated to the three strata, if we want optimum allocation using disproportionate sampling design?
	o)	The following are the number of departmental stores in 15 cities: 35, 17, 10, 32, 70, 28, 26, 19, 26, 66, 37, 44, 33, 29 and 28. If we want to select a sample of 10 stores, using cities as clusters and selecting within clusters proportional to size, how many stores from each city should be chosen?(Use a starting point of 10).
