Question During a long-distance kayak race series, a competitor traveled for a total of 48 kilometers over the course of 10 hours on two rivers. 6 kilometers were traveled on the first river, and 42 kilometers were traveled on the second river. On the first river, the competitor traveled at an average speed 4 kilometers per hour less than he traveled on the second river. What was the average speed of the competitor on the first river?

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.
