Biostatistics

a) Select a sample of size 15 by using simple random sampling. Write the procedure you followed W 27798 12511 20741 65030 72357 22780 04912 18963 65671 11784 26900 84444 85865 45148 64831 27098 11063 88498 Below is the random number table. 31487 79887 68845 98752 94998 07973 13069 10675 26184 23968 60896 07401 62310 49452 17655 40746 17555 71909 92052 34880 55229 56615 67552 41558 57146 17833 52135 during sample selection. Encircle the selected numbers as well. Make 5 clusters of the above random numbers. Cluster 1 contains the numbers starting from 0 & 1, cluster 2 contains the numbers starting from 2 8L 3, cluster 3 contains the numbers starting from 4 8t 5. cluster 4 contains the numbers starting from 6 & 7, cluster 5 contains the numbers starting from 8 & 9. Choose a sample of size 3 from each cluster using simple random sampling. Rearrange the above random numbers in ascending order. Using systematic sampling, select a sample of size 15. 69972; 80647: 40009- 37512- 87610- 29754: 28399 72997: 78002
