[br]Just select the distribution you want to work with from the list available in the drop down menu (e.g. Normal, Binomial) and [i]GeoGebra [/i]will graph it for you. Then, you can adjust the parameters of the distribution in the adjacent text boxes.

Just select the test you want to work with from the list available in the drop down menu (e.g. [i]Z Test of a Mean[/i]) and specify your [i]Null Hypothesis[/i], as well as your [i]Alternative Hypothesis[/i]. Then, adjust the parameters of your test in the provided text boxes and [i]GeoGebra [/i]will automatically provide the results of your statistical test.[/size]
