The graph below is the same as the previous dynamic Normal Curve. The graph in blue is the Standard Normal Curve with mean of 0 and standard deviation of 1. The red curve changes shape with different values for the mean and standard deviation as you move the sliders to change the values.[br]The AREA under the curves has been added here. Use the slider for the z score to find the area under the curve from - z to +z.
