Actually, even n=10 is really nothing, not being able to do that kind of calculations by hand reasonably quickly is more of a reflection of terrible basics, which isn’t surprising in American high schools.

For a stats class, even n=10 is tedious and absolute overkill. N=3 or 4 is entirely sufficient to prove the student understands the process.
