Which of the following statements are not true?
A) A general method for obtaining confidence intervals takes advantage of a relationship between test procedures and confidence intervals; a

100 ( 1 - \alpha )

% confidence interval for a parameter

\theta

Can be obtained from a level

\alpha

Test for

H _ { 0 } : \theta = \theta \text { versus } H _ { \pm } : \theta \neq \theta _ { 0 } \text {. }

B) To test

H _ { 0 } : \mu = \mu _ { 0 } \text { versus } H _ { \pm : } \mu \neq \mu _ { 0 }

Using the Wilcoxon signed-rank test, where

\mu

Is the mean of a continuous symmetric distribution, the absolute values

1 x _ { 1 } - \mu _ { 0 } 1 , \ldots . , 1 x _ { n } - \mu _ { 0 } 1

Are ordered from largest to smallest, with the largest receiving rank 1 and the smallest receiving rank n. Each rank is then given the sign of its associated

x _ { i } - \mu _ { 0 }

And the test statistic is the sum of the positively signed ranks.
C) For fixed

x _ { 1 } , \ldots \ldots , x _ { n } , \text { the } 100 ( 1 - \alpha ) \%

Wilcoxon signed-rank interval will consist of all

\mu _ { 0 }

For which

\mu = \mu _ { 0 }

Is not rejected at level

\alpha

Where

\mu

Is the mean of a continuous symmetric distribution.
D) All of the above statements are true.
E) None of the above statements are true.
