Facts: During an autopsy, the coroner is suspicious at how shallow the penetration is of a bullet in the chest of a victim. The bullet is only 1.7 inches deep. His conclusion is that this bullet struck the victim from a long range and had slowed down considerably before striking the victim. Refer to the data below relating the penetration depth for bullets at different speeds. Use the Excel program to create a scatter plot and display the linear formula. Use this formula to estimate the speed at which the bullet entered the body. Once you have that speed, use the formula Speed = 32*time
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.
