Solved: In Exercises 718, find the indicated area under the standard normal curve. If

Step 1 of 3

We note that the indicated region is the area to the left of the -score of  and to the right of the -score . Since the area represents a probability, we are interested in determining the probability that the -score is smaller than 3.4154155$.

We can find the probability  in the row starting with "0.6" and in the column starting with "04" in the standard normal table of the appendix.

The standard normal table in the appendix contains only -scores to the nearest hundredth. However, the -score  lies exactly in the middle between  and , then we will estimate the probability as the middle of the probabilities corresponding to the -scores  and .

We can find the probability  in the row starting with "3.4" and in the column starting with ".01" in the standard normal table of the appendix.

We can find the probability  in the row starting with "  " and in the column starting with "  in the standard normal table of the appendix.
