George calculates the F-ratio for a one-way ANOVA comparing the means of three groups: Group A (M = 4.12) , Group B (M = 7.37) and Group C (M = 8.92) . If he makes the decision to reject the null hypothesis, what is the most specific and appropriate conclusion he can make?
A) The groups are all different from each other.
B) The groups are not all equal to each other.
C) Group A ≠ Group B ≠ Group C
D) Group A < Group B < Group C
Null Hypothesis
