Your team was studying a process where fruit juice concentrate was packed in 300 ml cans. The cans were formed on a spinning machine before each was attached with a metal bottom panel. By inspection each can, you could determine whether, when filled, it could possibly leak. Working three shifts per day, the team took four (4) different samples every shift for two (2) consecutive days. Due to some technical issues such as machine speed, the team could not inspect the same number of cans each time sample was taken. Inspection results indicated that the number of cans with quality issues started to decrease by the end of the third shift of the first day.

Sketch clearly and accurately, an appropriate control chart depicting the case given above. Note: Your chart must have all the necessary features and follow all the conventions.
