public class MeanTestExperiment
extends Experiment
implements java.io.Serializable

The significance level, test mean, and type of test statistic (standard normal or student t) can by specified.

init

public void init()

This method initializes the experiment, including the slider for the parameters of the sampling distribution, the graph and table showing the reject random variable, the choice boxes for the type of sampling distribution, the type of test, the significnce leve, and the type of test statistic, and the toolbar.

Overrides:

init in class Experiment

getAppletInfo

public java.lang.String getAppletInfo()

This method returns basic information about the applet, including copyright information, descriptive information, and instructions.

Specified by:

getAppletInfo in interface IExperiment

Overrides:

getAppletInfo in class Experiment

Returns:

applet infomration

reset

public void reset()

This method resets the experiment, including the sampling random variable, the standard score variable, the test graph, the standard score graph, the reject graph and table, and the record table.

Specified by:
