Assume that the F ratio you've computed for the one-way ANOVA is 23. Which of the following can you conclude?
a. A computation error has probably been made (F values this high don't happen in real life)
b. The null hypothesis can be rejected at .05
c. The group means should have been spread far apart
d. There must have been extremely little within-group variability
e. The same size should have been large
