We review their content and use your feedback to keep the quality high. 68 Week 3 121 7. What is the total area under the normal distribution curve.

The function of a normal distribution is actually defined such that it must have a fixed value. Because the curve is symmetric that implies that the area under the curve from minus infinity to 0 is the same as the area from 0 to infinity namely ½. The normal distribution is a continuous probability distribution that is symmetrical on both sides of the mean so the right side of the center is a mirror image of the left side.
