The Normal Approximation to the Binomial
Use the sliders to adjust the values for n and p.
Use Point A to determine the P(X<xa).
Use the Checkbox for the Normal Curve to reveal and hide the normal curve.
What do you notice about the P(X<xa) when n is small?
What do you notice about the P(X<xa) when n is large?
How well does the Normal Curve estimate the area of the Binomial Curve when n is large? When n is small?
