Continued from the previous question:

For the "auto.lm$12"$ model, construct the third diagnostic plot, Scale$-$Location plot, and perform the non$-$constant variance test using the "ncvTest" function as follows:

plot$($auto$.$lm$12,$ which$=3)$

ncvTest$($auto$.$lm$12)$

Based on the plot and the test results, we conclude that

Group of answer choices

both the Scale$-$Location plot and the ncvTest indicate that the homoscedasticity assumption is violated.

the Scale$-$Location plot shows that the homoscedasticity assumption is violated; however, the ncvTest indicates no such violation.

the ncvTest indicates that the homoscedasticity assumption is violated; however, the Scale$-$Location plot shows no such violation.

neither the Scale$-$Location plot nor the ncvTest indicates that the homoscedasticity assumption is violated
