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
<h3>How to interpret the residual plot?</h3>
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
<h3>The estimated GPA</h3>
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
