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)

2. In a Single Factor ANOVA, which of the following is true?

• A. if the null hypothesis is rejected, it may still be possible that two or more of the population means are equal
• B. if the computed F-statistic exceeds the critical F-value we may reject H0 since there is insufficient evidence the treatment has no effect on the mean of the dependent variable
• C. if the computed F-statistic exceeds the critical F-value we will not reject H0 since there is sufficient evidence the treatment has an effect on the mean of the dependent variable
• D. all of the above
