1. Chapter 1 is pretty straight forward. Please make sure you
understand your simple summary statistics of a raw data set
(i.e., x, s 2 , ~ , quartiles, etc). Also, please understand the three

CHAPTER 2: PROBABILITY
A chance experiment, also called a random experiment, is simply
an activity or situation whose outcomes, to some degree, depend on
chance. To decide whether a given activity qualifies as a chance
experiment, ask
