... In Chapter 8, we will use sample statistics to estimate population parameters; in later chapters we’ll use sample data to answer questions (test hypotheses) about a population parameter. Two Types of Estimates for population parameters: 1) The population parameter can be estimated by one number: the ...

Drawing Inferences from Large Samples
... The problem of statistical inference arises when we wish to make generalizations about a population when only a sample is available. Once a sample is observed, its main features can be determined by the methods of descriptive summary discussed in Chapters 2 and 3. However, more often than not, our p ...
