A) a General

question 11

Multiple Choice

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.
