AQL of the raw material is key for sample size!

I recall that moving averages can help in understanding trends, but I’m not clear on how they relate to sample size determination in this context.

I feel like the 10% rule is a common guideline, but I’m not convinced it’s the best approach if quality is changing.

I think we practiced a question similar to this where we had to decide if the AQL was relevant. I wonder if it applies here too.

I remember discussing how sample size can be influenced by quality improvements, but I'm not sure if it should always decrease.
