For example if you are asked to find the area in the tail to the left of z -046 look up 046.

. Please enter the necessary parameter values and then click Calculate. The area under the normal curve from x a to x b with given mean and standard deviation is the probability that x assumes a value between x a and x b. You know Φa and you realize that the total area under the standard normal curve is 1 so by numerical conclusion.

If we are using Table IV in Appendix C we need to standardize the random variable x using the formula z. Using Normal Probability Table we obtain. Look in the z-table for the given z-value by finding the intersection.

Now subtract the smaller area from the larger area to find the area between the two z scores. Z3 is equivalent to 099882 area to the left of the z-score and. By subtracting both we can find the area under the standard normal distribution curve.
