BOB

Hey guys this is Alvin. I'm pretty nervous about the unit test, i dont think that im going to do well on it. i actually had a few muddy points, but right now my only concern is the confidence intervals. its still pretty blurry to me, but thanks to the blog, i think ill be alright.
I think that my strongest point is in the shadenorm(), i spent some time with it so it shouldnt give me any hickups.
