Course Description and Objectives. This course is a continuation of STAT:4100:0002. It is intended for upper-level undergraduate students in the mathematical sciences as well as for graduate students in all disciplines. The goal is to give students a solid foundation in the theory and methods of statistical inference. Main topics include point estimation, confidence intervals, convergence in distribution and convergence in probability, maximum likelihood methods, sufficient statistics, and testing of statistical hypotheses.
Prerequisites. STAT 4100.
Textbook. Introduction to Mathematical Statistics (8th ed.) Hogg, McKean and Craig,
(Prentice Hall). We will cover chapters 4 to 8.
Grading. Your semester grade will consist of the following components:
Homework
Quizzes
Midterm Exam 1 Midterm Exam 2
Total 100%
50% 10 highest out of 12
20% 4 highest out of 6
15% March 5 (in class, tentative) 15% April 16 (in class, tentative)
As a rough guide, A+,A,A-= 90%−100%, B+,B,B-= 80%−90%, C+,C,C-= 70%−80%, D+,D,D-= 60% − 70% .
Bonus points. To encourage participation in a virtual class, you will get 5 extra points towards your final grade if you do one of the following:
• actively ask/answer questions (at least 5 times);
• schedule a virtual meeting (around 10 minutes) with me to talk about your con-
cerns/suggestions on this class. You may also utilize the office hours.
Homework, Quizzes and Exams. Discussions on homework problems are encouraged during office hours, but I will not check whether your final answers are correct. Homework assignments are due on Wednesdays except for April 14. Quiz will be posted biweekly on
1
Fridays. You can do it at any time within a week, but there is a 30-minute time limit once you start. All exams will be open book, but you are not supposed to discuss with others. Attendance is required.

College of Liberal Arts and Sciences: Policies and Procedures
Absences and Attendance Students are responsible for attending class and for contributing to
the learning environment of a course. Students are also responsible for knowing course absence policies, which vary by instructor. All absence policies, however, must uphold the UI policy related
to student illness, mandatory religious obligations, including Holy Day obligations, unavoidable cir- cumstances, and University authorized activities (https://clas.uiowa.edu/students/handbook/attendance- absences). Students may use the CLAS absence form to aid communication with the instructor
who will decide if the absence is excused or unexcused; the form is located on ICON within the top banner under ”Student Tools.”
Academic Integrity All undergraduates enrolled in courses offered by CLAS have in essence agreed to the College’s Code of Academic Honesty. Academic misconduct affects a student’s re- lated grade and is reported to the College which applies an additional sanction including suspension. Outcomes about misconduct are communicated through UI email (https://clas.uiowa.edu/students/handbook/academic-fraud-honor-code).
Accommodations for Disabilities UI is committed to an educational experience that is acces- sible to all students. A student may request academic accommodations for a disability (such as a mental health, attention, learning, vision, and a physical or health-related condition) by register- ing with Student Disability Services (SDS). The student is then responsible for discussing specific accommodations with the instructor. More information is at https://sds.studentlife.uiowa.edu/.
Administrative Home of the Course The College of Liberal Arts and Sciences (CLAS) is the administrative home of this course and governs its add/drop deadlines, the second-grade-only op- tion, and related policies. Other UI colleges may have different policies for courses offered by that college. CLAS policies may be found here: https://clas.uiowa.edu/students/handbook.
Classroom Expectations Students are expected to comply with University policies regarding ap- propriate classroom behavior as outlined in the Code of Student Life (https://dos.uiowa.edu/policies/code- of-student-life/). This includes related UI policies and procedures that all students have agreed to regarding the COVID-19 pandemic. Particularly, each student must wear a face mask when in a UI building, including a classroom. The density of seats in classrooms has been reduced, and in some instances, this will allow 6 feet or more of distance while other cases, it may be less. Regardless, wearing a face mask and maintaining as much distance as is possible are vital to slowing the spread
of COVID-19. In the event that a student disrupts the classroom environment through the failure
to comply with a reasonable directive of an instructor or of the University, the instructor has the au- thority to ask that the student to leave the space immediately for the remainder of the class period. Additionally, the instructor is asked to report the incident to the UI Office of Student Account- ability, with the possibility of additional follow-up with the student. Students who need temporary alternative learning arrangements (TALA) for a future semester related to COVID-19 should visit
this website for more information: https://coronavirus.uiowa.edu/temporary-alternative-learning- arrangements-tala.

Class Recordings: Privacy and Sharing Some sessions of a course could be recorded or live- streamed. Such a recording or streaming will only be available to students registered for the course. These recordings are the intellectual property of the faculty, and they may not be shared or repro- duced without the explicit written consent of the faculty member. Students may not share these sessions with those who are not enrolled in the course; likewise, students may not upload recordings to any other online environment. Doing so is a breach of the Code of Student Conduct and in some cases is a violation of the Federal Education Rights and Privacy Act (FERPA).
Communication and the Required Use of UI Email Students are responsible for official correspondences sent to the UI email address (uiowa.edu) and must use this address for all com- munication within or with UI (Operations Manual, III.15.2).
Complaints Students with a complaint about an academic issue should first visit with the instruc- tor or course supervisor and then with the Chair of the department or program offering the course; students may next bring the issue to the College of Liberal Arts and Sciences. See this page for more information: https://clas.uiowa.edu/students/handbook/student-rights-responsibilities.
Final Examination Policies The final exam schedule is announced around the fifth week of classes; students are responsible for knowing the date, time, and place of a final exam. Students should not make travel plans until knowing this information. No exams of any kind are allowed the week before finals with a few exceptions made for particular types of courses such as labs or off-cycle courses: https://registrar.uiowa.edu/final-examination-scheduling-policies.
Nondiscrimination in the Classroom The University of Iowa is committed to making the class- room a respectful and inclusive space for people of all gender, sexual, racial, religious, and other identities. Toward this goal, students are invited in MyUI to optionally share the names and pro- nouns they would like their instructors and advisors to use to address them. The University of Iowa prohibits discrimination and harassment against individuals on the basis of race, class, gen- der, sexual orientation, national origin, and other identity categories set forth in the University’s Human Rights policy. For more information, contact the Office of Equal Opportunity and Diversity (https://diversity.uiowa.edu/eod; +1 319 335-0705 or (diversity.uiowa.edu)
Sexual Harassment Sexual harassment subverts the mission of the University and threatens the well-being of students, faculty, and staff. All members of the UI community must uphold the UI mission and contribute to a safe environment that enhances learning. Incidents of sexual harassment must be reported immediately. For assistance, please see https://osmrc.uiowa.edu/.
