6. Assume that there are 7 unfilled roles: 4 male and 3 female. There are 10 men, including Mark, and 7 women, including Anne, auditioning for a part in the play. (a) How many different casts are there? (b) How many different casts include Mark but not Anne? (c) How many different casts include Anne but not Mark. (d) How many different casts include both Anne and Mark? (e) How many different casts include neither Anne nor Mark? (f) Thinking about the numbers we found in the above parts as the number of elements in an event, how do the sets in (b), (c), (d), and (e) relate to the one in (a)?
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.
