A researcher reports the following information: F(3, 20) = 4.67. What is the correct decision?
A) Reject the null if α = .05 and retain the null if α = .01.
B) Retain the null if α = .05 and retain the null if α = .01.
C) Reject the null if α = .05 and reject the null if α = .01.
D) Retain the null if α = .05 and reject the null if α = .01.

The critical value for F(3, 20) at α = .05 is approximately 3.10. Since 4.67 > 3.10, we reject the null hypothesis at α = .05. For α = .01, the critical value is higher, so we retain the null hypothesis.
