Solution Steps

The question is asking for a true or false answer regarding the Wilcoxon rank sum test. Since this is a factual question, we can directly provide the answer.

Solution Approach

The Wilcoxon rank sum test is indeed a nonparametric test used to determine whether two independent samples were selected from populations having the same distribution. Therefore, the answer is "True."

Step 1: Understanding the Wilcoxon Rank Sum Test

The Wilcoxon rank sum test, also known as the Mann-Whitney U test, is a nonparametric test used to determine whether two independent samples come from the same distribution. It does not assume a normal distribution of the data.

Step 2: Interpreting the Question

The question asks whether the Wilcoxon rank sum test is used to determine if two independent samples were selected from populations having the same distribution. This is a factual statement about the test's purpose.
