public class MeanEstimateExperiment
extends Experiment
implements java.io.Serializable

This class models the interval estimation experiment in the standard normal model. A random sample from the normal distribution is simulated, and then an interval estimate of the mean is computed. The user can choose whether to compute the interval based on the standard normal statistic or the student t statistic. The confidence level and sample size can be chosen.
