**Understanding IQ Probability Distributions**Assume that adults have IQ scores that are normally distributed with a mean of \( \mu = 100 \) and a standard deviation \( \sigma = 15 \). To find the probability that a randomly selected adult has an IQ less than 115, follow these steps:1. **Accessing the Necessary Data:** - You will need to refer to a standard normal distribution table to find the probabilities. Links are provided: - [Click to view page 1 of the table.](#) - [Click to view page 2 of the table.](#)2. **Calculation:** - The task requires determining the cumulative probability up to an IQ score of 115. - Convert IQ score to a z-score, which is calculated by: \[ z = \frac{X - \mu}{\sigma} \] Where \( X \) is the IQ score, \( \mu \) is the mean, and \( \sigma \) is the standard deviation.3. **Result:** - You will input the probability value rounded to four decimal places into the provided field.**Note:** The exercise explores understanding statistical distributions and the use of z-tables to interpret real-world data.
