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.
