Post hoc tests with repeated-measures ANOVA Suppose that you conduct repeated-measures ANOVA with more than two treatment conditions and the null hypothesis is rejected. To determine exactly which mean differences are significant and which are not, you conduct post hoc tests. Which of the following statements about the use of Tukey's HSD test is correct? Tukey's HSD test can be conducted using HSD qv(MSwithin treatments/n) and using dfwithin treatments to find the value of q. Tukey's HSD test can be conducted using HSD qv(MSerr/n) and using dferr to find the value of q. Tukey's HSD test cannot be conducted.

Test for a significant difference in the treatment and block means using $\alpha=.01 .$ Bound the $p$ -value for the test of equality of treatment means. If a difference exists among the treatment means, use Tukey's test with $\alpha=.01$ to identify where the differences lie. Summarize your results. Answer the testing and estimation questions for Exercise $5 .$
