NOTE: One of the question sets has as potential answers things like mu, sigma, PART, sqrt(p(1-p)/n). The word PART is a mistake - some weird auto-correct function of e-learning I can't figure out how to fix right now. Whenever you see the word PART it should be the symbol "p" instead.
Because of this error the quiz will be open until Friday right before midnight and everyone has 4 chances at the quiz.

NOTES:

· These grades already include the 1 point for bubbling things correctly. If you did NOT get that point there will be a comment for you in e-Learning when you click on Exam 1.

· To make sure your grade was computed correctly carefully go over your exam and count the number of correct answers out of 33. Exam grades = (#correct)x3 +1

Example: 3 questions wrong: (30x3) + 1 = 91 OR (99-9) +1 = 91 BUT NOT (100-9) +1 = 92
