• A)The residual plot does not display a fan shape-- the residual plot is consistent with the claim of constant standard deviation.
• B)The scatterplot shows a linear trend-- the scatterplot is not consistent with the claim of constant standard deviation.
• C)The QQ plot mostly follows a straight line-- the QQ plot is consistent with the claim of constant standard deviation.
• D)The residual plot shows no trend-- the residual plot is not consistent with the claim of constant standard deviation.
