# impact on hypothesis if t-stat is equal to t-critical value for one-tail two-sample t-test? [duplicate]

I have a two-sample t-test where the t-statistic is equal to the critical t-value (at three decimal points) at a p-value of 0.05. does this mean i reject the null hypothesis or the opposite? thank you so much!

• This case: wilcox.test(c(1,4,5),c(2,3,6:12),alt="less") is an example of exactly 5% being achieved with a discrete test statistic (in this case for a one tailed test). In that case, you must reject the null for a test with a 5% type I error rate. [I find it helps to state the rejection rule and the implied type I error rate for the rejection rule you give.] – Glen_b Apr 15 '14 at 4:46
