Answer 1

22. In this case, the production manager has randomly collected 20 samples of 5 bags, throughout the day. The objective of the collection is to observe and ensure that all bags are filled with proper weight. The proper weight can be calculated using the UCL and LCL of the average number of bags in the system. A X-bar and R chart will be most appropriate in this situation as:

• The system deals with continuous data
• The data has been taken in form of samples of n=5
• The allowed weight of the rice bags can be based on UCL and LCL of the X and R chart

23. In this case, the hospital is analyzing the number of C-sections that were performed during each month and total number of births each month at the hospital. The total deliveries will include normal delivery, C-Section as well as IVF. An np Chart can be considered to be most appropriate in this scenario as:

• The system deals with attributes data
• The data can be further split into sub-categories like normal deliveries, C-section deliveries as well as IVF deliveries
• The data can be represented in form of percentage
• The subgroup type (type of delivery) is constant
