A) True, because the one-way ANOVA uses the F-statistic as the test statistic.
B) True, because rejecting the null hypothesis only indicates that there is a difference between at least two of the population means, but it doesn't specify which means are different or by how much.
C) True, because the degrees of freedom associated with the sum of squares for treatments is equal to the number of populations minus one.
Therefore, all three statements are true, making choice D the correct answer.
