365 people were surveyed as they left a basketball game at the Tucker center and the results were as follows: 150 attended the FSU Marist game. 205 attended the FSU Butler game. 160 attended the FSU NC State game. 55 attended the Marist game and the Nc state game. 65 attended the Nc state game and the Butler game. 60 attended the Butler game and the Marist game. 20 attended all three of the games. 1. How many attended only the FSU Butler game? 2. How many did not attend the Marist, Butler, or Nc state game? 3. How many attended at least 2 of the games? 4. How many attended the Marist and Butler games, but not the NC state game? 5. How many attended the Nc state or the Butler game?
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.
