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.

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.]
The indicated IQ score, \( x \), is [____]. (Round to one decimal place as needed.)
**Graph Explanation:**
The graph is a bell-shaped curve representing a normal distribution of IQ scores. It shows the shaded area under the curve to the right of a vertical line at \( x \), representing 0.8 of the distribution. The shaded area indicates the proportion of the population with IQ scores greater than the specified \( x \). The horizontal axis represents IQ scores, while the vertical axis is the relative frequency of those scores.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8d4281a1-138d-4154-9dd1-3fb4853cf3e0%2F8f2ba7ba-154f-4291-a520-08ae797b4295%2Fiwvdhqn_processed.png&w=3840&q=75)
