Multiple Choice

The data collected for studying whether or not there is a difference between the number of hours men and women watch television is summarized below. To compute the test value, the data from both samples
should be combined, arranged in order, and ranked according to each group. $\frac { 20 } { \mu _ { R } } , \frac { \sigma _ { R } } { }$ , and $z$ -test value for the Wilcoxon rank sum test started in problem 32 and continued in problem 37 .
