1.	An Engineering company wants to select several engineers to set up a special project team tobuild a bridge. All engineers in the company are divided into 3 groups according to theirprofessional skills and certain numbers of engineers are selected from each group to join the project team as follow:Professional skills of engineers P Q RTotal number of engineers 24 60 36Number of engineers selected 6 15 9(a) What is the population size? (b) Which sampling method is applied in this selection process? (c) What is the advantage of using the sampling method used in (b) above?
Answer» Explanation: a) The population size would be the sum of all engineers in the three groups. Population size = 24 + 60 +36 Population size = 120 b) Here quota sampling METHOD is used where every GROUP has a quota of 1/4th of its population c) The ADVANTAGES of quota sampling is that it is easier to conduct and manage. It takes less time to sample as the people are already subdivided

Answer»

Explanation:

a) The population size would be the sum of all engineers in the three groups.

Population size = 24 + 60 +36

Population size = 120

b) Here quota sampling METHOD is used where every GROUP has a quota of 1/4th of its population

c) The ADVANTAGES of quota sampling is that it is easier to conduct and manage. It takes less time to sample as the people are already subdivided
