Answer True or False. For each false statement,explain why the statement is false. I need the answercorrect and fast please.11. When testing for heteroscedasticity in a linear regression model it is preferable to use theBreusch-Pagan test, as it is able to detect non-linear forms of heteroscedasticity and hasfewer parameters to estimate in the auxiliary regression, compared to the White test.

The accompanying residual plot is also shown along with the QQ plot of the residuals. Choose the statement that best describes whether the condition for Normality of errors does or does not hold for the linear regression model. Choose the statement that best describes whether the condition for Normality of errors does or does not hold for the linear regression model. A.The residual plot displays a fan shape; therefore the Normality condition is not satisfied.B.The QQ plot mostly follows a straight line; therefore the Normality condition is satisfied.C.The scatterplot shows a negative trend; therefore the Normality condition is satisfied.D.The residual plot shows no trend; therefore the Normality condition is not satisfied.
