Quizplus · Accepted Answer

The two t-values that divide the area under the curve into a middle 0.95 area and two outside areas of 0.025 each (for a total of 0.05 outside the middle area) are symmetric around zero. This is characteristic of the t-distribution, which is symmetric. For df = 27, the critical t-values that correspond to the tails of 0.025 each (for a two-tailed test with a total alpha of 0.05) are indeed ±2.052.
