Chapter 6 - Sampling Distributions
In this Chapter we will begin our transition into inferential statistics.
Recall that in inferential statistics we use sample statistics to estimate
or make inferences about population paramet

In sections 7.2 and 7.3 we will learn how to construct condence
intervals for the population parameter . We will see how the
sample size n will play an important role in the method we will
use to create the condence interval. T

An event can sometimes be viewed as a composition of two or more
other events. These are called compound events and they can be formed
in two ways by union or intersection.
