Q9. Factory A produces 100 pieces of wooden legs used in manufacturing tables in 1 hour. The factory in total works for 3 hours.

1. Mean=10.3;Range=.3
2. Mean=10.1;Range=.8
3. Mean=10.2;Range=.6
4. Mean=9.9;Range=.5

Q10. In a quality management information system, there is a need to collect data and format such data into an information output that is useful to the project manager.

1. some information costs more to collect than it is worth
2. some information is not available for collection and input
3. most information relies on related data to generate the proper output
4. there is never enough information collected
5. the system is incapable of processing all the required information
