Answer:
1) 70%
2) 34,81%
Explanation:
Hello!
1)
The coefficient of determination R² is the percentage of the variability of the dependent variable (Yi) that is explained by the independent variable (Xi) under the simple linear model.
So your coefficient is R²= 0.6960 ≅ 0.70
70% of the sample variation in acceleration time is explained by the simple linear model.
2)
There is a mathematical coincidence between the coefficient of determination and the correlation coefficient (Person's r) if the correlation coefficient is squared, the coefficient of determination is obtained.
(r)²=R²
R²=(0.59)²= 0.3481
The coefficient of determination between Y and X is 34,81%.
I hope you have a SUPER day!
