Answer:
ŷ = -0.08522X + 157.7779
The slope = - 0.1
Intercept = 157.8
Step-by-step explanation:
Given the data :

General regression equation :
y = mx + c
Where
y = predicted variable
x = predictor / explanatory variable
m = slope or gradient
c = Intercept
The regression equation obtained ;
ŷ = -0.08522X + 157.7779
To one decimal place :
ŷ = -0.1X + 157.8
The slope = - 0.1
Intercept = 157.8
Total time taken to attach the wheels and hood to a car = 8.216 + 3.652 = 11.868 seconds
Total time taken to attach good and wheels to 425 cars = 11.868 x 425 = 4925.22 seconds
Ans. 4925.22 seconds
