olice, fire, and ambulance dispatchers, also called public safety telecommunicators, answer emergency and non-emergency calls. They work in emergency communication centers. Dispatchers must be available around the clock, so they often have to work evenings, weekends, and holidays. Overtime and long shifts - sometimes 12 hours - are common. Many states require dispatchers to become certified. The median annual wage for police, fire and ambulance dispatchers was $37,410 in May, 2014.

When a police radio dispatcher receives a call, he/she must determine the type of emergency and its location and decide the appropriate response on the basis of agency procedures. A small town has 6 police cars. When a radio dispatcher receives a call, depending on the nature of the situation, no cars, one car, two cars, three cars, four cars, five cars, or all six cars can be sent. How many options does the dispatcher have for sending the police cars to the scene of the caller?
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.
