5. A researcher is conducting a study on the palliative care of patients at a specific facility to determine how their chronic pain symptoms change after entering the palliative care environment. This study is aimed at determining the effectiveness of a standardized treatment protocol for the patients entering into the palliative care environment.

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.

A) We fail to reject Ho, which states the median difference in the pain scores before and after
treatment are equal because 40 is less than the critical value 6 for a Wilcoxon signed-ranks test
with a population of only 9 individuals.
B) We fail to reject Ho, which states the median difference in the pain scores before and after
treatment are equal because 40 is greater than the critical value 6 for a Wilcoxon signed-ranks
test with a population of only 9 individuals.
C) We reject Họ in favor of H1, which states the median difference in pain scores before and after
treatment are not equal because 1 is less than the critical value 6 for a Wilcoxon signed-ranks test
with a population of only 9 individuals.
D) We reject Họ in favor of H1, which states the median difference in pain scores before and after
treatment are not equal because 1 is greater than the critical value 6 for a Wilcoxon signed-ranks
test with a population of only 9 individuals.
