Round the F-ratio to three decimal places and the p-value to four decimal places. Assume all population and ANOVA requirements are met. F = P = What is the conclusion from the ANOVA? reject the null hypothesis: at least one of the group means is different fail to reject the null hypothesis: not enough evidence to suggest the group means are different
