In Single-Factor ANOVA, MSE Is the Mean Square for Error $H _ { o }$

In single-factor ANOVA, MSE is the mean square for error, and MSTr is the mean square for treatments. Which of the following statements are not true?

A) The value of MSTr is affected by the status of $H _ { o }$
(true or false)
B) When $H _ { o }$
Is true, E(MSTr) = E(MSE) = $\sigma ^ { 2 } \text { where } \sigma ^ { 2 }$
Is the common population variance.
C) When $H _ { o }$
Is false, E(MSTr) > E(MSE) = $\sigma ^ { 2 } \text { where } \sigma ^ { 2 }$
Is the common population variance.
D) The value of MSE is affected by the status of $H _ { o }$
(true or false) .
E) All of the above statements are true.
