I recall my first job. I worked for a man studying renal adenocarcinoma
in frogs as a model for human cancer (unless you'd prefer to induce cancer
in humans for research). I typed endless statistical analyses of the
data.

When I was in college I worked summers for the state Department of
Education. They crunched a lot of numbers trying to formulate state wide
high school exams that would result in a pleasing bell curve. Sometimes
they succeeded. The crunching part was quite literal since they used
Friden square root calculators;

That model isn't the square root variety but is very similar.

My memory of my statistics course was the chief use was determining how
many blivits you needed to test to insure only 5% of the blivits you
sold were junk. The 5% number varied depending on the cost of replacing
defective units and ****ing off customers.

It was a long time ago but my gut feeling is 1000 out of some 300+
million isn't a valid sample.
