Were students in the business and vocational high schools familiar with
proof
by induction? I have no figures whatever, but I posit that these populations
made up a large percentage (approaching 50) of the student population. I
base
this position on that 50% of students then were girls, and that many girls
were expected never to need such frippery as mathematical proof. Neither were
boy students taking business math or fundamental math. (Remember that
students
were supposed to master fractions before graduation, and if they hadn't
gotten
it by 9th grade then they kept at it.)

I'll see if I can come up with some real numbers.
