A Wilcoxon rank sum test for comparing two independent samples involves two samples of sizes 6 and 9. The alternative hypothesis is that the location of population 1 is to the left of the location of population 2. Using a 0.05 significance level, the appropriate critical values are 31 and 65.
Alternative Hypothesis
A hypothesis that contradicts the null hypothesis, indicating that there is a significant difference between specified populations.
Significance Level
Another term for level of significance, denoting the cutoff probability for determining when the p-value indicates a statistically significant result.
