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.

Expert Solution
Step 1
Part a:
From the provided data for traditional class we have,
Minimum value = 56.9
Maximum value = 86.2
Thus, range = Maximum value - Minimum value = 86.2 – 56.9 = 29.3
From the provided data for flipped class we have,
Minimum value = 63.4
Maximum value = 92.6
Thus, range = Maximum value - Minimum value = 63.4- 92.6 = 29.2
The traditional course has a range of 29.3, while the flipped course has range of 29.2.
The traditional course has more dispersion.
