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

<u>ANSWER</u>
See attachment for the graph
<u>EXPLANATION</u>
The standard equation of the vertical ellipse with center at the origin is given by
where
The ellipse has its vertices at (0,±17).
This implies that:a=±17 or a²=289
The foci are located at (0,±15).
This implies that:c=±15 or c²=225
We use the following relation to find the value of b²
We substitute into the formula for the standard equation to get:
