Find the indicated IQ score. 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 0.85 The indicated IQ score, x, is (Round to one decimal place as needed.)
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.

**Question:**
Enter the indicated IQ score \( x \) in the field provided. Ensure you round your answer to one decimal place as necessary.
- **The indicated IQ score, \( x \), is:** [_____]
**Diagram Explanation:**
The diagram is a normal distribution curve illustrating IQ scores. The curve is marked with a shaded region in green, representing a probability. This region is associated with a value of 0.85, indicating the area under the curve to the left of the score \( x \).
