Normal Approximation to the Binomial How it works: Students can change the binomial parameters n and p and see the effect on a bar plot representing the binomial probabilities. The approximating normal distribution (mean np and variance np(1-p)) is overlaid so they can determine when the approximation is good. |
<param name=normaloverlay value="true"> - If this value is "true", the normal density will be overlayed on the graphic.
