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. Statistical inference may be divided into two major areas: Parameter estimation Hypothesis testing
