In a one-way ANOVA, what is the conclusion if the computed F statistic is greater than the critical F value? A.Reject H0 since there is evidence all the means differ. B. Do not reject H0 since there is no evidence of a difference in the means. C.Reject H0 since there is evidence that not all the means are the same. D. Do not reject H0 because a mistake has been made.

In a one-way ANOVA, if the computed F statistic exceeds the critical F value, we should reject H0 since there is evidence that all the means differ reject H0 since there is evidence that at least one of the means is different from the others not reject H0 since there is no evidence of a difference in means not reject H0 because a mistake has been made.

In a one-way ANOVA, what does it mean to reject the statement in the null hypothesis if three treatment groups are being compared? Choose the correct answer below. A. Rejecting the statement in the null hypothesis means that there is insufficient evidence to conclude that the mean of one of the populations is different than the other two or that all three populations are different. B. Rejecting the statement in the null hypothesis means that there is sufficient evidence to...
