For the Wilcoxon rank sum test,the quantity T₁ is defined as A)the total sum of ranks minus. B)the sum of ranks in the larger sample. C)the total sum of ranks. D)the sum of ranks of the values in the smaller sample.

Question

T₁ represents the sum of ranks of the values in the smaller sample, which is also known as the test statistic in the Wilcoxon rank sum test. This is because the test compares the ranks of observations from two independent samples and checks if they come from the same distribution or not. The sum of ranks in the smaller sample is used to compute the test statistic, which is then compared to a critical value from a reference distribution to obtain the p-value for the test. Therefore, choice D is the correct answer.
