Do male and female finches in the wild have similar weight distributions? Researchers measured the weight (in grams) of a random sample of finches caught in the wild. Here are the results: males 15.7 15.9 16.7 19.1 20.8 females 14.7 15.4 15.5 16.8 18.6 19.3
Given the small sample sizes, we prefer using a nonparametric procedure to determine whether males and females differ in weight. Let W, the Wilcoxon rank sum test statistic, be the sum of the ranks assigned to the males' weights.
What is the value of W?
