Find the area of the shaded region. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15 Click to view page 1 of the table. Click to view page 2 of the table. The area of the shaded region is (Round to four decimal places as needed.)

Step 1 ：The question is asking for the area under the curve of a normal distribution, which is equivalent to finding the probability of a certain range of values. In this case, the shaded region is not specified, so I'll assume it's asking for the area under the entire curve. The area under the entire curve of a normal distribution is always 1, because it represents the total probability of all possible outcomes.

Step 2 ：Final Answer: The area of the shaded region is \(\boxed{1}\).
