There are five numbers in a data set. They are 1, 2, 18, 19 and x, where x is one of the largest two number of the five. What value does x need to be so that the median of the five numbers equals the mean of the five numbers?
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.

The five numbers are 1,2,18, 19, and x.
Here, x is the one of the largest two number of five.
Median is (n+1)/2 th item.
Median is the 3rd data point.
Since x is one of the two largest number, Median =18
