White people: IQ 100, SD 15.

Black Americans: IQ 80, SD 15.

18,300 astronaut applications to NASA for 14 spots=0.08% acceptance rate.

A minimum requirement is having a bachelor's in a STEM field. Biology majors have the lowest IQ of these, averaging 121.

I don't know if the reported 18,300 applicants is before or after the junk applications were thrown away, so I don't know if the average IQ of an astronaut applicant is 121 or 100, which is the number I would guess if the 18,300 number was before unqualified applications were tossed.
