I would put dots where I want 1 standard deviation to be, because I know that's where the inflection points are. (I just graphed $y=e^{-x^{2}/2}$ on desmos, and I see that the inflection points are at a height of about 60% of the maximum, so that's about 3/5ths of the way up. But I didn't do that step back when I taught statistics.) And then the curve is ...

Perhaps you could make a stencil out of cardboard, which you could trace onto the board. However, I wonder about the pedagogical value of perfectly accurate drawings. There is an important ...

Given you seem to have zero exposure to this material, I would just look for a reasonable undergrad text. I would avoid classes "for business" or the like (although really they are way better than nothing!) I would also be a little careful about asking for "mathematical statistics". Some people may interpret that as asking for a hyper ...
