A Wilcoxon rank sum test for comparing two independent samples involves two samples of sizes 6 and 10. The alternative hypothesis is that the location of population 1 is different from the location of population 2. Using a 0.05 significance level, the appropriate critical value is 32.
Wilcoxon Rank Sum Test
A nonparametric statistical test used to compare two independent groups to assess whether their populations have the same distribution.
Alternative Hypothesis
The hypothesis that proposes a difference or effect, in contrast to the null hypothesis, which assumes no effect or difference.
Significance Level
The probability of rejecting the null hypothesis in a statistical test when it is actually true, often denoted by alpha (α).

Final Answer :
True
Explanation :
The Wilcoxon rank sum test uses critical values from a table depending on the sample sizes and level of significance. In this case, with sample sizes of 6 and 10 and a significance level of 0.05, the appropriate critical value from the table is 32. Therefore, the statement is true.
