Answer:
Driver 1 score: 9
Driver 2 score: 3
Step-by-step explanation:
We are given the following in the question:
The number of marks scored on a driving test are y(x) is a dependent variable and the number of drinks taken by the driver is the independent variable(x).
Slope, m = -3
y-intercept,c = 18
Then, we can write the regression equation as:
![y(x) = mx + c\\y(x) = -3x + 18](https://tex.z-dn.net/?f=y%28x%29%20%3D%20mx%20%2B%20c%5C%5Cy%28x%29%20%3D%20-3x%20%2B%2018)
Driver 1 consumed 3 drinks.
We put x = 3 in the regression equation.
Thus, the predicted driving 1 score for driver 1 is
![y(3) - -3(3) + 18\\y(3) = 9](https://tex.z-dn.net/?f=y%283%29%20-%20-3%283%29%20%2B%2018%5C%5Cy%283%29%20%3D%209)
Driver 1 predicted score is 9.
Driver 2 consumed 5 drinks.
We put x = 5 in the regression equation.
Thus, the predicted driving 2 score for driver 2 is
![y(5) - -3(5) + 18\\y(5) = 3](https://tex.z-dn.net/?f=y%285%29%20-%20-3%285%29%20%2B%2018%5C%5Cy%285%29%20%3D%203)
Driver 2 predicted score is 3.
