1. Critical Issues (Numerical/Statistical Errors)

1.1 Wrong Formulas

  1. ~~9-5-ci-cb-sigma-unknown.rst:275-276~~ – FIXED. Standard error corrected from sigma/n to sigma/sqrt(n).

  2. ~~6-4-normal-distribution.rst:146,150,321,622,644,1042~~ – FIXED. Normal PDF normalizing constant corrected from 1/sqrt(2*pi*sigma) to 1/(sigma*sqrt(2*pi)) at all 6 locations.

  3. ~~11-4-comparing-two-means-independent-unpooled.rst:142-144~~ – FIXED. One-sided p-value formulas corrected: removed incorrect absolute values from upper-tailed and left-tailed formulas.

  4. ~~12-4-multiple-comparison-procedures-family-wise-error-rates.rst:151-154~~ – FIXED. Boole’s inequality derivation corrected: P(No Type I error) → P(At least one Type I error), union of error events, P(Type I error for Test l) = alpha.

  5. ~~13-2-simple-linear-regression.rst:865~~ – FIXED. Correlation formula corrected from s_{XX} to s_{XY}.

  6. ~~13-3-diagnostics-inference.rst:739~~ – FIXED. Added missing = sign between general formula and numerical substitution.

  7. ~~13-3-diagnostics-inference.rst:358~~ – FIXED. Alternative hypothesis label corrected from H_0 to H_a.

  8. ~~10-2-ht-for-mean-sigma-known.rst:235~~ – FIXED. Alternative hypothesis label corrected from H_0 to H_a.

  9. ~~5-5-covariance-of-dependent-rvs.rst:471~~ – FIXED. Variance formula coefficient corrected from ab2 to 2ab.

  10. ~~4-6-independence-of-events.rst:225~~ – FIXED. Circuit reliability formula corrected: P(L_2') → P(L_3') in third factor.

  11. ~~4-6-independence-of-events.rst:77~~ – FIXED. “general addition rule” corrected to “general multiplication rule.”

1.2 Wrong Numerical Values

  1. ~~5-6-binomial-distribution.rst:296~~ – FIXED. “0.1 successes” corrected to “1 success” (E[X] = np = 1).

  2. ~~5-6-binomial-distribution.rst:335~~ – FIXED. “9.9 successes” corrected to “9 successes” (E[X] = np = 9).

  3. ~~5-7-poisson-distribution.rst:282-284~~ – FIXED. Joint probability P(X1=1, X2=4) corrected: first factor changed from P(X>1)=0.8009 to P(X1=1)=0.1494; final answer corrected from 0.1346 to 0.0251.

  4. ~~6-1-continuous-rvs-and-pdfs.rst:284,313~~ – FIXED. Conditional probability label corrected from P(X < 0.8 | X < 1) to P(X > 0.8 | X < 1) at both locations.

  5. ~~11-5-mean-of-paired-differences.rst:304-339~~ – FIXED. Six difference signs corrected in data table (rows 1, 3, 4, 5, 6, 8 flipped to negative).

  6. ~~11-5-mean-of-paired-differences.rst:1019~~ – FIXED. P(T_11 > 14.65) corrected to P(T_11 > 13.87).

  10. ~~10-1-ht-errors-and-power.rst:650~~ – FIXED. = 1497 = 1517 corrected to = 1497 + 20 = 1517.

  11. ~~10-2-ht-for-mean-sigma-known.rst:959,964~~ – FIXED. z_TS corrected from 1.977 to 1.976 at both occurrences.

  12. ~~12-2-sources-of-variability.rst + 12-3-f-test.rst~~ – FIXED. Root cause: MSE=99.8 was rounded from 99.75, causing cascading errors when back-computing SSE. Fix: 12-2 restructured to give SSE=19451 (data-derived) instead of MSE; both files now use consistent values (SSE=19451, SSA=8834, MSE=99.75, MSA=2208.5, F=22.14).

  17. ~~3-3-measures-of-variability-range-variance-and-SD.rst:437~~ – FIXED. (9-6.11)^2 corrected to (19-6.11)^2.

  18. ~~3-3-measures-of-variability-range-variance-and-SD.rst:445~~ – FIXED. Denominator corrected from 9 to 8 (n-1).

  19. ~~3-3-measures-of-variability-range-variance-and-SD.rst:787~~ – FIXED. sqrt argument corrected from 3721.87 to 3,682.5636.

  20. ~~2-2-tools-for-categorical-qualitative-data.rst:238~~ – FIXED. Dept B frequency corrected from 307 to 370.

  21. ~~3-4-measures-of-variability-IQR-and-5-number-summary.rst:815-868~~ – FIXED. Recomputed with R type-7: Q3 3.9, IQR 1.5, all four fences, outlier classifications (8.5 now extreme), and Q2-to-Q3 distance (0.9).

  22. exam2_fall2025.rst:513-525 – p-value 0.1805 should be 0.1163. Already addressed with correction admonition in source.

  23. final_fall2024.rst:546-549 – P(No OH) 0.7657 should be 0.7606. Already addressed with correction admonition in source.

  24. final_spring2025.rst:178-181 – Answer key (B) should be (D). Already addressed with correction admonition in source.

  25. final_fall2025.rst:623-627 – 4900/110 = 45.5455 should be 44.5455. Already addressed with correction admonition in source.

  26. final_fall2025.rst:1062-1065 – Prose r = 0.8580 should be 0.8736. Already addressed with correction admonition in source.

1.3 Conceptual Errors

See items 3, 4, and 11 above (absolute-value p-value formulas, Boole’s inequality derivation, addition-vs-multiplication rule).

2. Convention Violations

~~2.1 Binomial Normal Approximation~~ — CLOSED (not strict)

Both forms (np(1-p) >= 15 and np >= 10 AND n(1-p) >= 10) are introduced in lecture; students use their own judgement. No changes needed.

~~2.2 Hypothesis Test Conclusion Phrasing~~ — CLOSED (downgraded)

Preferred: “The data give [strong] support (p-value = …) to the claim that…” or “The data do not give [strong] support…”

Banned (must fix): “accept H0”, “prove”. No instances of these were found in the audit.

Not preferred but acceptable (no action needed): “sufficient evidence” (8 instances), “statistically significant” (16 instances), exam phrasing (1 instance). These 25 instances are retained for awareness but do not require correction.

~~2.3 “Statistically Significant” in Conclusions~~ — CLOSED

~~2.8 Histogram Format (Density + Red KDE + Blue Normal)~~ — CLOSED (not worth changes)

~~18 non-compliant histograms from Chapter 3 onward.~~ Instructor decision: histogram KDE/overlay inconsistencies are not important enough to warrant changes.

~~2.9 LINE Assumption Presentation~~ — ALL FIXED

Added per-assumption role attribution at all 5 locations, distinguishing CLT-robust procedures (parameter estimation, CIs for mean response, hypothesis tests) from non-robust ones (prediction intervals). Added .. _robustness-normality: label in 13-4 and cross-references from 13-2 and 13-3.

~~2.10 Internal Consistency: Robustness Guidelines~~ — FIXED

  • ~~9-5-ci-cb-sigma-unknown.rst:921-926~~ – Exercise 8 solution used n=30 boundary; corrected to match the authoritative lecture table thresholds (n < 15 / 15 ≤ n < 40 / n ≥ 40).

  • ~~11-5-mean-of-paired-differences.rst:1598~~ – T/F Q6 answer changed from “True” to “False” with explanation consistent with 11-1 Exercise 8 Q4: “before and after” only requires paired analysis when the same individuals are measured at both times.

3. Build/Formatting Issues

3.1 Sphinx Build Warnings

87 warnings total from /tmp/sphinx_build_output.txt, grouped by type:

~~Undefined substitution references (7 errors)~~ — ALL FIXED

All 7 bare |text| patterns wrapped in :math: roles: |z_TS| → :math:\|z_{TS}|`, |z|→:math:`|z|`, |r|→:math:`|r|``.

~~Markdown-style tables parsed as RST line blocks (6 tables)~~ — ALL FIXED

All 6 markdown-style tables converted to RST list-table directives: 11-4 (1 table), 11-5 (1 table), 4-5 (3 tables), 8-5 (1 table).

~~Title level inconsistencies (3 CRITICAL warnings)~~ — ALL FIXED

Removed overlines from Exercises headings in 9-1, 9-2, 9-3 so they use underline-only === consistent with the main section titles.

~~List-table column mismatch (1 error)~~ — FIXED

exam1_spring2026.rst: :widths: updated from 11 values to 12 values to match column count.

~~Inline markup issues (1 warning)~~ — FIXED

exam2_spring2025.rst:662: Added space between :math:\t`and-test` to prevent RST inline markup collision.

~~Explicit markup ends without blank line (1 warning)~~ — FIXED

9-1-intro-statistical-inference.rst:909: Added blank line before ---- transition.

~~Duplicate target names (~40 warnings)~~ — CLOSED (BY DESIGN)

Intentional: seasonal exam navigation files (regular/summer/winter variants) share target names because JavaScript switches which variant is active based on the current term. Only one variant is rendered at a time.

~~Duplicate labels (3 warnings)~~ — CLOSED (BY DESIGN)

Same reason: winter-variant exam files (exam1-winter.rst, final_exam-winter.rst, exams_index-winter.rst) intentionally duplicate labels from the regular-semester files for the JS season switcher.

~~Toctree references to nonexisting documents (6 warnings)~~ — FIXED

Toctree entries in final_exam.rst and final_exam-summer.rst used final_fall2024 etc. but the files are in the FinalExam/ subdirectory. Changed to FinalExam/final_fall2024, FinalExam/final_spring2025, FinalExam/final_fall2025 in both files.

~~Documents not included in any toctree (6 warnings)~~ — FIXED / CLOSED

Items 1-3 (FinalExam files): resolved by the toctree path fix above. Items 4-6 (winter variants): intentionally orphaned — the JS season switcher handles their inclusion at runtime.

~~Title underline too short (1 warning)~~ — FIXED

~~Missing standard “Exam Information” admonition header~~ — FIXED. Added .. admonition:: Exam Information with :class: info, metadata (Course/Semester/Points/Time), and Problem/Total Possible/Topic table to all 4 files (exam1_fall2024, exam1_fall2025, exam1_spring2024, exam1_spring2025). Titles updated to match Exam 2 format. PDF links preserved inside admonition.

4. Code Issues

~~4.1 Tidyverse Violations~~ — CLOSED

Tidyverse usage in 2-2-tools-for-categorical-qualitative-data.rst is acceptable — the graphs are complex enough that tidyverse saves substantial space. R reference section item (tibble::tibble()) is intentionally introducing additional topics.

~~4.2 Base R Plotting Violations~~ — CLOSED

R reference section uses base R plot() intentionally to demonstrate diagnostic functions. Worksheet 8 uses plot() for mathematical PDF/CDF curves (Uniform, Exponential), which is appropriate for function visualization. Worksheet 1 prose references are introductory guidance.

6. Cross-Document Inconsistencies

  1. ~~Binomial approximation rule~~ — CLOSED. Both forms taught in lecture; students use own judgement.

  2. ~~Robustness thresholds~~ — FIXED. Exercise 8 solution corrected to match lecture table (n=40 boundary). (See §2.10.)

  3. ~~F-statistic in Ch12 coffeehouse example~~ — FIXED. Both files now use consistent data-derived values (F=22.14, MSA=2208.5, MSE=99.75).

  4. ~~Exercise 5 sd/t in 11-5~~ — FIXED. All values corrected to s_D=1.623 and t=13.87.

  5. ~~LINE assumption treatment~~ — FIXED. All 5 locations now distinguish CLT-robust procedures from prediction intervals. (See §2.9.)

  6. ~~Hypothesis label (H_0 vs H_a)~~ — FIXED. Both 10-2:235 and 13-3:358 corrected.

  7. ~~Tukey CI lower bound in 12-4~~ — FIXED. Root cause: MSE=99.8 (should be 99.75) and arithmetic errors in CI endpoints. Updated MSE to 99.75, recomputed both inline CIs (Bonferroni and Tukey) and all 10 rows of the results table.

  8. ~~Conclusion phrasing~~ — CLOSED. “Sufficient evidence” and “statistically significant” are acceptable per instructor.
