Below is the scatterplot showing the association between raw material (in tons) put into an injection molding machine each day (x), and the amount of scrap plastic (in tons) that is collected from the machine every 4 weeks (y). The residual plot of the data is also shown along with a QQ plot of the residuals.
Choose the statement that best describes whether the condition for linearity does or does not hold for the linear regression model.
◦ The residual plot shows no trend--the residual plot
is consistent with the claim of linearity.
◦ The residual plot does not display a fan shape--the residual plot
is consistent with the claim of linearity.
◦ The residual plot shows a horizontal trend--the residual plot
is not consistent with the claim of linearity.
◦ The QQ plot mostly follows a straight line trend--the QQ plot
is consistent with the claim of linearity.
