In Exercise 11.30 you calculated the average of the nine cell variances. How does that answer compare to the MSerror from Exercise 13.23?

Obtain the Tukey test for Dosage from the analysis of variance in Exercise 13.23. Interpret the results.

Use any statistical package to run the two-way analysis of variance on Interval and Dosage for the data in Epineq.dat on the Web site. Compare the results you obtain here with the results you obtained in Chapter 11, Exercises 11.28–11.30.
