Answer:
For this case we define the dependent variable as Y and the independent variable X. We assume that we have n observations and that means the following pairs:
For this case we assume that we want to find a linear regression model given by:
Where:
represent the estimated slope for the model
represent the estimated intercept for the model
And for any estimation of the dependent variable is given by this model.
The difference between the observed value of the dependnet variable and the value predicted using the estimated regression equation is known as residual, and the residual is given by this formula:
So the best option for this case is:
d. residual

Answer:
17.67 mpg
Step-by-step explanation:
The fuel efficiency is given by :
We need to find the fuel efficiency for a speed of 30 mph
Put the value of s equals 30 mph in the above equation.
So, the required fuel efficiency is equal to 17.67 mpg.
