The table summarizes results from 985 pedestrian deaths that were caused by automobile accidents.
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.
![### Analysis of Pedestrian Accident Data
The table below summarizes results from 985 pedestrian deaths that were caused by automobile accidents. The data is categorized based on the intoxication status of both the driver and the pedestrian.
#### Pedestrian Accident Data Table
| Driver Intoxicated? | Pedestrian Intoxicated? | | |
|---------------------|-------------------------|-----|-----|
| | | Yes | No |
| Yes | | 58 | 69 |
| No | | 221 | 637 |
#### Probability Calculation
If one of the pedestrian deaths is randomly selected, calculate the probability that either the pedestrian was intoxicated or the driver was intoxicated.
#### Instructions
- Report the answer as a percentage rounded to one decimal place.
- There's no need to enter the "%" symbol.
