The 5 number summary of a data set is 23-63-72-78-88. What percent of the data lies between 72 and 78? Enter your answer as a whole number percent.
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 5-number summary is defined as, the minimum value, the lower quartile, the median, the upper quartile and the maximum value.
The lower quartile is a value below which 25% of the observations lies and above which 75% of the observations lie. Similarly, the upper quartile is the value below which the 75% of the observations lie and above which the 25% of the observations lie. In addition, the median is a value below which 50% of the observations lies and above which 50% of the observations lie.
