Official course sources
Independent, original, free self-study practice. Not affiliated with or endorsed by this university; these are not official exam questions. Topic alignment does not establish transfer credit, a current section’s weekly syllabus, full course coverage or a grade prediction. Follow your instructor’s rules and use official course materials for assessed work. No live AI chat or paid access is required.
What is not covered
Computational foundations only. Graphs, experimental design, software labs, ANOVA, two-sample t/Welch and regression inference are not covered. Normal/z cases explicitly assume known population SD; t exercises cover one sample and paired differences with supplied critical values.
