Method Summary

void	doExperiment() This method defines the experiment.
void	itemStateChanged(java.awt.event.ItemEvent event) This method handles the choice events associated with a change of distribution type, test type, significance level, or state of knowledge of mu.
void	reset() This method resets the experiment.
void	setDistribution() This method sets up the scroll bars and graphs when the type of distribution changes.
void	setParameters() This method computes the upper and lower critical values and sets up the graphs when the distribution changes.
void	step() This method runs the experiment one time, playing a sound that depends on the outcome.
void	update() This method updates the graphs and tables.
void	update(java.util.Observable o, java.lang.Object arg) This method handles the scroll events associated with a change in sample size or a change in the parameters of the distribution.
