Which of the Following Statements Are True?
A) in Large-Sample $Z = \frac { S _ { + } - n ( n + 1 ) / 4 } { \sqrt { n ( n + 1 ) ( 2 n + 1 ) / 24 } }$

question 48

Multiple Choice

Which of the following statements are true?

• A) In large-sample problems, the Wilcoxon signed-rank test is never very much less efficient than the t test and may be much more efficient if the underlying distribution is far from normal.
• B) The Wilcoxon signed-rank test statistic for large-sample is \(Z = \frac { S _ { + } - n ( n + 1 ) / 4 } { \sqrt { n ( n + 1 ) ( 2 n + 1 ) / 24 } }\)
• Where n is the sample size and \(S _ { + }\)
• Is the sum of the ranks associated with the positive observations.
• C) When the sample size n > 20, the Wilcoxon signed-rank test statistic \(S _ { + }\)
• Has approximately a normal distribution with mean and variance given by \(n ( n + 1 ) / 4 \text { and } n ( n + 1 ) ( 2 n + 1 ) / 24\)
• , respectively
• D) All of the above statements are true.
• E) None of the above statements are true.
