If the F statistic is greater than 1.0 the rejection region is in the left tail if the value is less than 1.0 the rejection region is in the right tail?

The F statistic is used in ANOVA and regression analyses to compare variances. If the F statistic is greater than 1.0, it suggests that the variance between groups is larger than within groups, and the rejection region would typically be in the right tail of the distribution. Conversely, if the F statistic is less than 1.0, it indicates that the variance within groups is larger, placing the rejection region in the left tail. Thus, the correct interpretation is that the rejection region for the F test is in the right tail regardless of the value being greater or less than 1.0.
