hello there is a mistake in problem on session-64-numerical-integration page in the problem , at the bottom of the page: i think it should be H(x) = 1 / (σ (2π)^(1 / 2)) ℯ^((-1) / 2 T(x)²) with T(x) = (x - μ) / σ try the link below ForEveryBody (file://ORTOLLJ-PC/Users/ortollj/Google%20Drive/ForEveryBody) in the problem text download (free) Geogebra, 5.6 and not 2.8 ? integral H(x) must be <=1 !
