Example of finding an area that extends from minus infinity (∞) to a point to the right of the mean—To find the area under the normal curve, you must know how many standard deviations that point is to the right of the mean. Then the area under the normal curve can be read directly from the normal table. For example, the total area under the normal curve for a point that is 1.55 standard deviations to the right of the mean is 0.9394.
