Page 5 of 13 a) What is the population of interest and state population size? [Hint: the supervisor is only interested to inspect Asus Brand and not all the PC that are being imported] (2 marks) b) What are the first three Asus laptops that will be selected for review using a simple random sampling procedure? Use the random Numbers Table provided below. Select the sample starting at the first digit of row 1 and working along the row. Show 3 steps procedure.
