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.
