Question

1. The rejection region for the Single Factor ANOVA

A. can be located in either the upper-tail of the F-distribution or the lower-tail of the F-distribution

B. is located in the upper-tail of the F-distribution, since only large F-values support alternative hypothesis (that the treatments have an effect on the population means)

C. is located in the lower-tail of the F-distribution, since only relatively small F-values support alternative hypothesis (that the treatments have an effect on the population means)

D. is located in the upper-tail of the Z-distribution, since only large z-values support alternative hypothesis (that the treatments have an effect on the population means)

Explanation / Answer

If F cal > F critical we reject the null hypothesis.

ie., can be located in either the upper-tail of the F-distribution or the lower-tail of the F-distribution
