Based on this histogram, draw the ogive (the cumulative relative frequency polygon) for the spin rate data.
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 professional golfer is shopping for a new brand of golf ball. He likes most
of the features of one particular brand, but he wants to make sure that the
brand has a desirable spin rate (the rate at which the ball spins on its axis
after being struck by a golf club). To test the spin rate of this new brand of A
ball, the golfer hits the brand of ball on 100 five-iron shots, and a computer
measures the spin rate for each shot. The computer then produces the
following histogram summarizing the 100 spin rates:

polygon) for the spin rate data.
