The F-test is used to determine whether there is a significant difference between the means of two or more groups. If the F-value is large (i.e. greater than the critical F-value), it indicates that the differences between the group means are large relative to the variability within each group. This suggests that the grouping variable is likely to be a significant factor in explaining the differences in means. Therefore, option C is the correct choice.
