The mean number of pages per day in June is 14, and the mean number of pages per day in July is 27. The difference in the means is 13 pages per day. The MADs for June and July are both 3.5.
Which statement best describes the difference of the means for the two months in terms of the mean absolute deviation (MAD) for each data set?
The difference in means is not meaningful because the means are separated by about 1 MAD.
The difference in means is meaningful because the means are separated by about 4 MADs
The difference in means is not meaningful because the means are separated by about 0.5 MADs.
The difference in means is meaningful because the means are separated by about 3 MADs.

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?
