Evil stats homework is done!

Aaaaaaah, just printed twenty-six pages!!! Now keeping my fingers crossed that those answers are correct (rather, mostly correct -- just being realistic). It's so annoying to get bits and pieces from all over the world, it seems, instead of having a good example to go by and just apply a different situation. No, I am not promoting "teaching to the test" -- however, this is only a homework and should be a good chance to practice, not a test of ability to collect advice from friends, coworkers, etc.
