In a Wilcoxon rank sum test for independent samples, the two sample sizes are 4 and 6, and the value of the Wilcoxon test statistic is T = 25. If the test is a two-tail and the level of significance is 0.05, then the null hypothesis will be rejected.

Given the sample sizes (4 and 6), the critical value for a two-tailed test at the 0.05 significance level from Wilcoxon rank sum tables does not match the provided test statistic (T = 25) for rejecting the null hypothesis. The exact critical values depend on tables or software, but typically, for such small sample sizes, a test statistic of 25 would not be extreme enough to reject the null hypothesis at the 0.05 level.
