A) When $3 \leq m \leq n \leq 8$

Multiple Choice

Which of the following statements are not true?

A) When m and n (number of observed x values and y values, respectively, in the combined sample) exceed 8, the Wilcoxon rank-sum test statistic W has approximately a t distribution with m + n - 1 degrees of freedom
B) The table of critical values for the Wilcoxon rank-sum test, which is available in your text, gives information only for $3 \leq m \leq n \leq 8$
Where m and n are the number of observed x and y values, respectively, in the combined sample.
C) If m and n are the number of observed x and y values, respectively, in the combined sample, then to use the table of critical values for the Wilcoxon rank-sum test, which is available in your text, the X and Y samples should be labeled so that $m \leq n .$
D) As with the Wilcoxon signed-rank test, the common practice in dealing with ties when using the Mann-Whitney test is to assign each of the tied observations in a particular set of ties the average of the ranks they would require if they differed very slightly from one another.
E) All of the above statements are true.
