Errata for Linear Model Theory: With Examples and Exercises, by Dale L. Zimmerman (2020), Springer.

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 5.2-12: The known solution to this exercise requires some background in complex analysis, which is otherwise not a prerequisite for the book, so this exercise, though correct, really should not be included in the book. It will be removed in future editions.
3. Page 199: A better title for Section 5.5 would be "Distributions Associated with Sampling from Normal Distributions"
4. Page 273: In the pdf displayed four lines from the bottom, the entire denominator should be multiplied by pi.
5. Page 274: Wherever theta appears in Example 6.4-10, replace it with beta.
6. Exercise 6.4-21: The upper limit of support for x should be plus infinity, not theta.
7. Exercise 7.6-10: Symbols a, b, and c should be beta1-hat, beta2-hat, and beta3-hat, respectively.
8. 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.
9. 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.
10. Page 471: In the second line from the bottom, replace "the first test" with "the second test"
