1. The graph shows the data for the time it takes Jerome to bike to school, based on his average biking speed for that trip. Which sentence describes the association? A As the average speed increases, so does the time he takes to get to school. 60 40 20 20 40 As the average speed increases, the time he takes to get to school decreases. C The speed he bikes at does not affect the time it takes him to get to school. D The speed he bikes at affects the time it takes him to get to school, but it is unclear if the time increases or decreases
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.
Option B is correct
As the average speed increases the time he takes to get the school decreases
Explanation:
On the graph it showed that plotted point is decreasing as the average speed increasing,
