Abstract

Samples are collected and analyzed to estimate population characteristics. Chapter 3 explores the practice of inference: how hypotheses about what may be true in the population are tested and how population parameters are estimated with confidence intervals. Included in this chapter are tests of hypotheses and confidence intervals for: (i) A population mean from a single sample, (ii) The difference between means of two populations, or segments from two independent samples, and (iii) The mean difference within one population between two time periods or two scenarios from two matched or paired samples.
