MEASURES OF CENTER: Start with the data values of 74 and 187. Identify three additional data values such that the resulting sample has a mean of 100. Additional values: A. Values: 39, 180, 20 B. Values: 80, 79, 78 C. Values: 0, 70, 190 D. Values: 45, 79, 140
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.

Additional values:
| A. |
Values: 39, 180, 20 |
|
| B. |
Values: 80, 79, 78 |
|
| C. |
Values: 0, 70, 190 |
|
| D. |
Values: 45, 79, 140 |
Solution:
From the given information, the two data values are 74 and 187.
Let the additional values are 39, 180 and 20.
Then, the mean is
Thus, the correct option is A.
