I think the prediction from Karl's observation is that if the obtained t is 1.0999783 and the critical t is 1.1113, then many students would make a mistake in choosing which was larger. I am gob-smacked. Karl's observation, if true, might explain many things that until now have been

Part of the problem is that Elementary Education is the last haven for college math phobes. I remember the Dean of the School of Education (the biggest producer of teachers in Minnesota) asking that his students be excused from the institutional mathematics requirement. On Sep 29, 2012, at
