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.
Find these values
![**Mathematical Fractions and Operations**
**a.**
\[ \left\lfloor \frac{7}{8} \right\rfloor \]
The expression uses floor brackets which typically represent the floor function. The floor function refers to the greatest integer less than or equal to the given fraction. In this case, the fraction is \(\frac{7}{8}\).
**b.**
\[ \left\lfloor \frac{1}{2} \right\rfloor + \left\lceil \frac{3}{2} \right\rceil \]
This expression includes both floor and ceiling functions:
1. The first part uses floor brackets with the fraction \(\frac{1}{2}\).
2. The second part uses ceiling brackets with the fraction \(\frac{3}{2}\).
The floor function \(\left\lfloor \cdot \right\rfloor\) finds the largest integer not greater than the fraction, while the ceiling function \(\left\lceil \cdot \right\rceil\) finds the smallest integer not less than the fraction.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcd9c5d72-9ea9-48a4-9d31-06ed7f5c0ae4%2F119bb858-7003-435d-80f9-7cec812c536a%2Fhx49q1_processed.png&w=3840&q=75)
