Which of the following charts should be used to monitor leaks in plastic bottles?

Show Suggested Answer Hide Answer
Suggested Answer: C

The P chart, also known as the proportion chart, is used to monitor the proportion of defective items in a process. For leaks in plastic bottles, which are attribute data (defective or not), the P chart is appropriate as it helps track the fraction of defective units over time.

Honestly, I'm just happy there's no 'all of the above' option. That always trips me up on these exams!

Hold up, what about the np chart? Isn't that designed for counting defects? Seems like a better fit than the P chart to me.

Hmm, I'm not so sure. Isn't the P chart more suitable for attributes data like pass/fail? Seems like the logical choice here.

I think option B is the way to go. X and s charts are perfect for monitoring process variability, which is exactly what we need for leak detection in plastic bottles.

X and s charts are definitely the way to go for detecting process variability in this case.
