3. Chegg Study and Course Hero: These platforms have user-uploaded, step-by-step explanations for specific problem numbers. Cross-check for errors, as community content varies in quality.
4. Tutoring Centers: Your campus tutoring center likely has answer keys for common textbooks, including Devore.
5. Open Educational Resources (OER): Some professors publish their own detailed solutions for selected problems from the 8th edition on their university web pages.

Warning: Be cautious of free PDFs from unknown websites. Many contain incorrect formulas, missing pages, or malware. Always verify a solution against the textbook’s appendix for critical values.

How to Use Solutions to Prepare for the FE Exam

For engineering students, the Fundamentals of Engineering (FE) Exam includes a statistics section. If you use the 8th Edition Devore Solutions correctly, you are also preparing for this licensure exam.

Strategy:

1. Cover the solution with a sheet of paper.
2. Solve the problem using only the FE-approved calculator (TI-36X Pro or Casio fx-115ES).
3. Uncover the solution. Did you get the same p-value?
4. If Devore’s solution uses a manual formula (e.g., ( t = \frac\barx - \mus/\sqrtn )) and you used a calculator’s built-in test, ensure the assumptions match.
