The administration at Center City Community College has formed a 19-person planning committee. There are three times as many administrators as there are students and four more faculty members than students. Assuming that there are only administrators, students and faculty members on the committee, how many students are there on the committee? Do not try to solve each problem algebraically. Instead, make a guess that satisfies one or more conditions of the problem and then evaluate your guess
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.

Keep adjusting your guesses until you have a solution that fits all the conditions of the problem.
