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:
Driver 1 consumed 3 drinks.
We put x = 3 in the regression equation.
Thus, the predicted driving 1 score for driver 1 is
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
Driver 2 predicted score is 3.
