Provide an appropriate response. 8) The frequency table below shows the number of days off in a given year for 30 police detectives. Days off | Frequency 0-2 10 3-5 1 6-8 7 9-11 7 12-14 1 15-17 4 Construct a relative frequency histogram.
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.
Let's first draw the table as follows
| Days Off | Frequency | Relative Frequency () |
| 0-2 | 10 | |
|
3-5 |
1 | |
| 6-8 | 7 | |
| 9-11 | 7 | |
| 12-14 | 1 | |
| 15-17 | 4 | |
| =30 |
