Confidence Interval

Introduction

The statistical inference is the process by which sample results are used to derive conclusions about the characteristics of a population. This process allows us to estimate characteristics not known as the population parameters that characterize the distribution of the variable of interest There are two basic approaches to estimation that estimates point and interval estimates for a point estimator (i.e. a function of sample data) that is defined at the order to provide a synthesis of a parameter of interest.

An estimator for interval is an interval constructed around the point estimator, in such a way that ...
