In the previous chapter we illustrated how
a parameter can be estimated from sample
data. However, it is important to understand
how good is the estimate obtained.
Bounds that represent an interval of
plausible values for a parameter ar

7-1 Introduction
The field of statistical inference consists of
those methods used to make decisions or to
draw conclusions about a population.
These methods utilize the information
contained in a sample from the population in
drawing conclusions.
