Select the true statements) about a one-way ANOVA test. If we reject the null hypothesis in a one-way ANOVA, there is evidence to suggest that the underlying population variances are unequal. In a one-way ANOVA, all sample sizes must be the same in order for the test statistic to be valid. In a one-way ANOVA, we reject the null hypothesis for large values of F or for values of F close to 0. If we reject the null hypothesis in a one-way ANOVA, there is evidence to suggest that all pairs of population means are unequal. In a one-way ANOVA, the k population variances are assumed to be
