Normal distribution & cumulative probability

You can explore the properties of the normal distribution by varying the slider that determines the width of the distribution and the slider that determines the mean of the distribution. You can then explore the cumulative probability between Xmin and Xmax by dragging the green and red points. If you are using a laptop or desktop computer please run this as a Java applet - see option below window - be patient - it may take a while to load the Java version - if you see an "unresponsive script" message - choose "continue"
