Hypothesis Tests, Confidence Intervals and Simulation to Infer Population Characteristics and Differences
We study a sample to estimate population characteristics. Chapter Three explores the practice of inference: how we reliably test hypotheses about what may be true in the population and estimate population statistics 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.
