The Normal Distribution Curve

The APP below is designed to help you interact with a normal distribution. The mean position and standard deviation can both be dynamically adjusted. In addition, the proportions associated with regions above, below, or in between two points, A and B, which can be adjusted as needed, are given by selecting the appropriate checkbox below. Hint: change the values of B and C by clicking on the points and using the cursor keys rather than dragging the points.
