Small F test statistics indicate that the decision is to reject the null hypothesis of equal means.

Step-by-step explanation:

In Anova tests or regression analysis, in cases where we have equal variances, the ratio is expected to be 1. However, the population variance is tested to be equal in the course of running a small F-test. The small F-test statistics is that value obtained when a regression analysis or ANOVA test is ran in order to determine where the mean of two separate populations are different to a significant extent. Hence F-tests do not indicate decision to reject null hypothesis of equal means.
