a. Service is the single best predictor of the
price.
It will be able to explain most of the variation in the meal
price.
b. Regression equation.
The coefficient in the simple regression is 2.940059
c.
Coefficient of determination(rsqaure) =
0.8677557
It is the measure of the amount of variability in y explained by x.
Its value lies between 0 and 1. Greater the value, better is the
model. In this case, it 86.7%, hence the model is good
