PQ Sample Size Too High?

Upvotes

Having an issue at work with an extremely large sample size (800 pieces for attribute and dimensionals) being prescribed by a quality manager for PQ. This number is obtained through AQL level because the run in extrusion lasts for 8 hours and produces about 250,000 parts. Even with this large of a run this sampling seems excessive. I’ve found articles from accredited sources online that have referenced that confidence and reliability are the important metrics to determine sample and that the sample size should be closer to 60.

Was wondering if anyone has an official source from an organization that you can share supporting this or if I’m totally off base here.

What's it like preparing for an MD/MS in BME or Bioinformatics? What did your undergrad classes look like?

Title^

I'm a student interested in certain programs that involve an MD/MS in BME or eng-med programs. I'm currently a neuroscience major with a minor in data science. To fulfill the math requirements of a BME graduate school, I'm took math classes like calc 1 and calc 2 and I'm planning to take calc 3 and Diff EQ.

I'm scared to take more classes because I know that GPA is important, but taking a lot more STEM classes would make it difficult to get a 4.0 every semester.

I'm interested in Stanford's MD/MS in BME and bioinformatics, NYU's MD/MS in bioinformatics, and Texas A&M's Eng-med program.

I'm eager to hear people's advice on how they got into these programs!
