Which five values would be used to graph a box-and-whisker plot for the following set of data?

36, 14, 27, 27, 33, 22, 41, 29
these are the answers below
14, 22, 27, 33, 41
14, 24.5, 28, 34.5, 41
20.5, 29, 30, 31.5, 36
14, 22, 27, 33, 36

Here is their argument. given the obtuse angle x, we make a quadrilateral abcd with ∠dab = x, and ∠abc = 90◦, and ad = bc. say the perpendicular bisector to dc meets the perpendicular bisector to ab at p. then pa = pb and pc = pd. so the triangles pad and pbc have equal sides and are congruent. thus ∠pad = ∠pbc. but pab is isosceles, hence ∠pab = ∠pba. subtracting, gives x = ∠pad−∠pab = ∠pbc −∠pba = 90◦. this is a preposterous conclusion – just where is the mistake in the "proof" and why does the argument break down there?
