Which of the Above Statements Are Not True?
A) a T

Which of the above statements are not true?

A) A t variable obtained by standardizing $\hat { \beta } _ { 0 } + \hat { \beta } _ { 1 } x ^ { + }$
Leads to a confidence interval and test procedure concerning
(the expected value of Y when $x = x ^ { + }$
) )
B) The variable T = $\left[ \hat { Y } - \left( \beta _ { 0 } + \beta _ { 1 } x ^ { +} \right) \right] / S _ { \dot { y } }$
Has a t distribution with n - 1 degrees of Freedom, where n is the sample size and $x ^ { + }$
Is a specified value of the independent variable x.
C) A 100 $( 1 - \alpha ) \%$
Confidence interval for
; the expected value of Y when $x = x ^ { + }$
, is given by
Where n is the sample size.
D) All of the above statements are true.
E) None of the above statements are true.
