Ise the information and table that follows to complete problems 1-10. Roulette is a casino game in which a wheel with sections numbered 0-36 is spun in one direction, and a small ball is spun onto the wheel in the opposite direction. In order to win, players must guess which number on the wheel the ball will land on. A well-balanced roulette wheel has a mean of 18. The following table shows the results of 5 sample sets from 5 different roulette wheels labeled A-E, obtained by spinning the ball 12 times on each roulette wheel. Wheel Spin results A 1 35 3 27 14 11 16 29 0. 19 18 35 В 17 28 4. 29 19 25 10 26 27 23 28 25 4 30 9. 16 0. 25 34 31 14 18 32 D 32 20 10 17 35 17 18 26 3 18
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.
