The residual plot does not show a linear model and the estimated GPA of a student who studies for 15 hours a week is 3.17

How to interpret the residual plot?

The figure (1) represents the residual plot.

In the residual plot of a linear model, the line of the plot is represented by a horizontal line

From the figure, the line of the plot is not an horizontal line.

Hence, the residual plot does not show a linear model

The estimated GPA

The number of hours is given as:

x = 15 hours

The regression line is given as:

y = 0.134x + 1.16

Substitute 15 for x

y = 0.134 * 15 + 1.16

Evaluate

y =3.17

Hence, the estimated GPA of a student who studies for 15 hours a week is 3.17
