How tall is A?

[manujchandra]

Greetings!

I have a few questions regarding ThinkBayes2/solutions/height_soln.ipynb

Why do we update the suit with 0? Why not 'A'?

'suite.Update(0)'

Also, the question asks:

Suppose I choose two residents of the U.S. at random. A is taller than B. How tall is A?

We know A is taller than B, yet in Posterior marginal distributions, we see the mean height of B is greater than A.

3. How do we interpret the results? Should we say A is 164 cm tall since the question asks how tall is A?

Thanks!
