Which of the Following Statements Are True?
A) the Assumptions $\hat { \beta } _ { 1 }$

Which of the following statements are true?

A) The assumptions of the simple linear regression model imply that the standardized variable
Has a t distribution with n - 2 degrees of freedom.
B) The estimated standard error of $\hat { \beta } _ { 1 }$
; namely
, will tend to be small when there is little variability in the distribution of $\hat { \beta } _ { 1 }$
And large otherwise.
C) There is an estimated standard error for the statistic $\hat { \beta } _ { 0 }$
From which a confidence interval for the intercept $\beta _ { 0 }$
Of the population regression line can be calculated.
D) The most commonly encountered pair of hypotheses about the slope $\beta _ { 1 }$
Of the population regression line is $H _ { 0 } : \beta _ { 1 } = 0 \text { versus } H _ { \pm } : \beta _ { 1 } \pm 0$
E) All of the above statements are true.
