When you submit your homework, include the links to the five new pages you've added to the Compendium.
Of course, before you add, search it to make sure your problems don't already exist!
Write a couple of paragraphs reflecting on the situation you're in when, after training, some totally unexpected event occurs. Think of the day when the chicken finally gets its head cut off, or the day when the meteor comes and kills off the dinosaurs, or when 9/11 happens and everyone concludes that now there's a "new normal" where planes will be highjacked every other day. When this happens, how do you distinguish between this being the first sample drawn from a totally new distribution versus the stars having happened to align a certain way, allowing the freak accident to occur.
