Textbook Question
Chapter B.5, Problem 1AYU

Explain why the critical value of t, one-tailed, alpha = .05 is the same as the critical value of t, two-tailed, a .10 .
If I have 2 for the degrees of freedom with an alpha of 0.05, what would be the critical value of t?
With α = .05 and df = 8, the critical values for a two-tailed t-test are t = ±2.306. Assuming all other factors are held constant if the df value were decreased to df = 5, what would happen to the size of the critical regions?
