Comparing the calculated F statistic of 2.70 with a critical F value at the p = 0.05 level for 3 and 48 degrees of freedom shows that the calculated F value is not significant. Therefore, we fail to reject the null hypothesis and conclude that no significant differences are indicated among the groups.
