The alternate hypothesis in ANOVA states that at least one population mean is different, not that they are all equal. Rejection of the null hypothesis in ANOVA indicates that there is a difference, but it does not specify which means differ. If the computed F value is greater than the critical value, we reject the null hypothesis, meaning not all means are equal.
