Concepts Of Interval Estimation And Quality Control Charts Via Computer Simulated Sampling

Resumen

The interconnection between confidence interval estimation and statistical decision making with control charts is discussed. The concepts of confidence in interval estimation and statistical process control are presented with the aid of plots of the results of simulated sampling. Plots of confidence intervals with known standard deviations and with estimated standard deviations and a control chart are presented. Data that were used by Gosset (1908) with the introduction of the t-distributions are used for an example with historical import.
