Question
### Understanding IQ Probability

**Context:** This exercise helps illustrate the concept of probability in a normal distribution, using IQ scores as a practical example.

**Problem Statement:**

Assume that adults have IQ scores that are normally distributed with a mean (\(\mu\)) of 100 and a standard deviation (\(\sigma\)) of 15. The task is to find the probability that a randomly selected adult has an IQ between 81 and 119.

**Instructions:**

1. You are provided with a table (accessible via links) to assist in solving the problem.
2. Calculate the probability that an adult’s IQ falls within the specified range (81 to 119).
3. The answer should be an integer or a decimal, rounded to four decimal places as needed.

**Interactive Elements:**

- There are clickable links to view page 1 and 2 of a table that provide necessary data for calculations.
- Space to input your answer and a button to check if the solution is correct after inputting your answer.
- There is a progress indicator displaying "All parts showing."

**Note:**

Understanding how to apply the concepts of mean, standard deviation, and normal distribution will enable solving problems like these, which have practical implications in fields like education and psychology.
