Q.1 In population of size N=20, the observation were 4, 7, 10, 14, 17, 18, 20, 24, 25, 27, 29, 30, 34, 37, 39, 40, 42, 45, 47, 48. Draw Random Sample of size 5 form given population using SRSWOR. Q.2 In population of size N= 10, the observation were 1, 4, 7, 12, 15, 17, 20, 24, 27, 29. Draw Random Sample of size 5 form given population using SRSWR. Q.3 Population size of 3 Strata A, B, C are 100, 200, 300 respectively. Draw a sample of size 30 from an entire Population. i) Obtain how many units are to be selected from strata A, B, C. ii) Using Random numbers, draw random sample of above obtained size from each strata. Q.4 Draw a random sample of size 50 from a population of 1000 workers in a
