Answer
1.
In the question, it is mentioned that the height of the jump depends on the weight of the bike.
Hence,
Independent quantity - Weight(pounds) Variable that represents this quantity - w
Dependent quantity - Height(inches) Variable that represents this quantity - h
Does the data appear to be linearly related? Yes
Below is the plot of the data using the tool.
2.
Using the regression tool, the linear equation that models the data is
The slope value is -0.16.
The y-intercept value is 13.35.
3.
Interpretation of the slope
If the weight of the bike increases by 1 pound, then the model predicts that the height of maximum jump decreases by approximately 0.16 inch.
The model predicts that the height of maximum jump decreases as weight increases.
4.
The correlation coefficient of the model is
The correlation is strong.
5.
The maximum jump height of a bike weighing 25 pounds is
