He invokes Excel as an analytical engine several times in this story. I am trying to figure out if he actually considers it to be a powerful statistical engine, or if he is merely using it synecdochically for the benefit of non-technical readers, in order to represent statistical software more generally.

It actually is the de-facto-standard modeling engine in a lot of areas, even some scientific areas, but mainly economics/finance. There are some pretty nuttily complex simulations written entirely in Excel, with the visualization part of the simulation done by popping up a chart--- you can even make it animated by popping up a new chart at a certain time interval. There's even a market in commercial spreadsheets, which you buy and load sort of like libraries: http://www.palisade.com/RISK/

Not necessarily a good idea, but somehow it caught on. One possible reason is that it was one of the earlier widely available pieces of software for doing declarative, dependency-based modeling that auto-propagates updates: if box A and box B are linked by a "B = 2*A", then B auto-updates whenever A changes, without you manually writing a propagate-updates loop. You can now do stuff like that in a lot of languages, but it's relatively recent (e.g., it's one of the new features JavaFX variables have).

I couldn’t sleep at night. I’d fill up a bathtub and scream into it. Eh, what? Do (normal) people do this? Is it because it absorbs the sounds or something?

I'd never heard of it before. I too assumed that muting the sound was the idea, he mentioned he was staying at a hotel, so I guess screaming would have raised some serious suspicion. I wonder if the sound would travel down the drainpipe, though.

hmm... while I was backpacking on the PCT the term 'scream into a lake' was used (for when you got really mad).

Ever talk or scream in a pool? Muffled, distant sound, but is still there.

The 'Solver' (http://www.solver.com/) tool in Excel is widely used for many business optimization problems. If you have x & y quantities of two raw materials and products A and B consume different proportions of each raw material, then you can use the solver to determine the most optimal production strategy that maximizes your profit (or minimizes your labor requirements etc.)
