Homework 7: Problem 9.3 (analyze on the log scale), Problem 9.5 (do Tukey's 1-df-for-nonadditivity test and test for the significance of polynomial cisplatin dosage contrasts/terms, if warranted, possibly after transforming the dosages to 0,1,2,3,4,5), Question 9.1 (do for the balanced two-factor case, with variances as given in class).

Homework 9: Exercises 11.2(a), 11.4, 11.6, Problem 11.2 (Analyze the data on a transformed scale, where you select the transformation using the Box-Cox method. The residuals from the analysis of the transformed data may not look normal, but ignore that fact for the purposes of this problem.), Exercise 12.4, due Wednesday, April 7
Homework 10: Problems 12.1 (the "standard five questions" are listed at the beginning of Section 12.10), 12.4, 12.6, Exercise 13.2, Problem 13.8, due Monday, April 19

Errata for Probability and Statistical Inference, by R. V. Hogg, E. A. Tanis, and D. L. Zimmerman, 10th edition (2020): Pearson

1. Exercise 2.4-11: It should say "... and verify that it is positive if p < 0.5, zero if p = 0.5, and negative if p > 0.5."
2. Exercise 6.4-21: The upper limit of support for x should be plus infinity, not theta.
3. Exercise 7.6-10: Symbols a, b, and c should be beta1-hat, beta2-hat, and beta3-hat, respectively.
4. Exercise 7.6-11: This exercise is correct, but out of place. Part (a) asks for the (sample) correlation coefficient, which is not defined until Section 9.6.
5. Exercise 7.7-6: This exercise is also correct but out of place as it involves calculation of the sample correlation coefficient, which is not defined until Section 9.6.
