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 increased to df = 20, what would happen to the critical values for t?
A)They would increase (move farther from zero).
B)They would decrease (move closer to zero).
C)They would stay the same.
D)not enough information to answer

As the degrees of freedom (df) increase, the critical values for a t-distribution move closer to zero, reflecting a distribution that more closely resembles the normal distribution.

With α = 05 and Df = 8, the Critical Values for a Values
