Is there any relation between the Air Bag installed and survival? What is the intensity? i. Calculate the odds of being killed in a harmful event car accident for a vehicle withand without air bags. Interpret the two odds. iv. Calculate the odds ratio of being killed in a harmful event car accident with andwithout air bags. What does this ratio tell you about the importance of having airbags in a vehicle?
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.
