Course Goals
Course Outcomes
 Read mathematical statistics methods.
 Do mathematical statistics problem solving.
 Gain ideas to do statistical computations.
 Perform estimation techniques to capture information from data and into their analysis.
 Use MOM, MLE, MVUE to do parameter estimation and inference.
 Use Chisquared test to evaluate the homogeneity of populations.
 Use Chisquared test to evaluate the independence of categorical variables.
 Use Chisquared test to evaluate the goodnessoffit of data to a specified distribution.
Advice on how to read/approach the materials: Always read the material covered in class again on your own immediately before the next class. Reading means understanding each sentence in the class notes and textbook and then solving problems on them effectively on your own. Next, be able to solve most of the remaining related problems on your own.
Policies
DMS Course Policies: All DMS students must familiarize themselves with, and adhere to, the Department of Mathematical Sciences Course Policies, in addition to official universitywide policies. DMS takes these policies very seriously and enforces them strictly.
Grading Policy: The final grade in this course will be determined as follows:
Homework 
15% 
Class Participation (see rubric, below) 
15% 
Midterm Exam I 
20% 
Midterm Exam II 
20% 
Final Exam 
30% 
Your final letter grade will be based on the following tentative curve. NOTE: Your final letter grade will be based on a curve that ensures at least few A’s. Practice problems, HW and Quiz assignments are posted on Math 341 Course Moodle page. Note that Homework assignments may be modifications of questions in the textbook. Homework is generally due within a week unless announced otherwise by the instructor. Solutions to the assignments will be handed out in class and discussed (see the Math 341 Course Moodle page). Late homework cannot be accepted, since the solutions are already handed out.
Attendance Policy: Attendance at all classes will be recorded and is mandatory. Please make sure you read and fully understand the Math Department’s Attendance Policy. This policy will be strictly enforced. Absence will affect the grade due to class participation requirement (15% of the grade).
Homework Policy: No late homework will be accepted.
Calculator Policy: Calculators are allowed but should be basic, without graphing capabilities, algebraic simplification capabilities, formulastoring capabilities and without other such capabilities.
Exams: There will be two midterm exams held in class during the semester and one comprehensive final exam. Exams are held on the following days:
Midterm Exam I 
March 7, 2019 
Midterm Exam II 
April 11, 2019 
Final Exam Period 
May 10  16, 2019 
The final exam will test your knowledge of all the course material taught in the entire course. Make sure you read and fully understand the Math Department's Examination Policy. This policy will be strictly enforced.
Makeup Exam Policy: There will be No makeup QUIZZES OR EXAMS during the semester. In the event an exam is not taken under rare circumstances where the student has a legitimate reason for missing the exam, the student should contact the Dean of Students office and present written verifiable proof of the reason for missing the exam, e.g., a doctor’s note, police report, court notice, etc. clearly stating the date AND time of the mitigating problem. The student must also notify the Math Department Office/Instructor that the exam will be missed.
Laptops: Computers and other communication devices should remain closed during lecture time, exams and quizzes.
Grading: Any complaints regarding grading have to be presented immediately after receiving the graded test, quiz, HW or exam inclass.
Looking into neighbors work during exams: Keeping eyes hidden using hats, caps, etc., from the proctor, but not from the neighbors work during exams is not allowed.
Wandering: Going in and out of the classroom often is not allowed. (Let instructor know ahead of time that if one is coming late or leaving a classroom in session early due to extenuating circumstances).
Cellular Phones: All cellular phones and other electronic devices must be switched off during all class times.
Additional Resources
Math Tutoring Center: Located in the Central King Building, Lower Level, Rm. G11 (See: Spring 2019 Hours)
Further Assistance: For further questions, students should contact their instructor. All instructors have regular office hours during the week. These office hours are listed on the Math Department's webpage for Instructor Office Hours and Emails.
All students must familiarize themselves with and adhere to the Department of Mathematical Sciences Course Policies, in addition to official universitywide policies. The Department of Mathematical Sciences takes these policies very seriously and enforces them strictly.

Grade Criteria for Class Participation (out of a maximum of 4)
Once the student names are uniquely identified, from there onwards each student will receive a score of 0 to 4 at the end of the each class according to the following criteria:
0: Student is absent (please give proof of extenuating circumstance). Student has sustained attention on laptop/electronic devices. Not participating in the class at all. She/he is disruptive and says little or nothing in class. Contributions in class reflect inadequate preparation. Ideas offered are seldom substantive, provides few if any insights, and never a constructive direction for the class. Integrative comments are absent. If this person were not a member of the class, valuable classtime would be saved.
1: Student is present and not disruptive. Tries to respond when called on but does not offer much. Student demonstrates very infrequent involvement in class discussion. This person says little or nothing in class. Hence, there is not an adequate basis for evaluation. If this person were not a member of the class, the quality of discussion would not be changed.
2: Student demonstrates adequate preparation: knows basic facts, but does not show evidence of trying to interpret or analyze them. She/he offers straightforward information (e.g., straight from the textbook), without elaboration or very infrequently (perhaps once a class). Does not offer to contribute to discussion, but contributes to a moderate degree when called on. Student demonstrates sporadic involvement. Contributions in class reflect satisfactory preparation. Ideas offered are sometimes substantive, provides generally useful insights but seldom offer a new direction for the discussion. If this person were not a member of the class, the quality of discussion would be diminished somewhat.
3: Student demonstrates good preparation: knows covered course material well, has thought through implications of them. She/he offers interpretations and analysis of course material (more than just facts) to class. Student contributes well to discussion in an ongoing way: responds to other students' points, thinks through their own points, questions others in a constructive way, offers and supports suggestions that may be counter to the majority opinion. Student demonstrates consistent ongoing involvement. Contributions in class reflect thorough preparation. Ideas offered by the student are usually substantive; provide good insights, and sometimes direction for the class. If this person were not a member of the class, the quality of discussion would be diminished.
4: Student demonstrates excellent preparation: has analyzed covered course material exceptionally well, relating it to readings and other material (e.g., readings, course material, etc.). She/he offers analysis, synthesis, and evaluation of covered course material, e.g., puts together pieces of the discussion to develop new approaches that take the class further. Student contributes in a very significant way to ongoing discussion: keeps analysis focused, responds very thoughtfully to other students' comments, contributes to the cooperative argumentbuilding, suggests alternative ways of approaching material and helps class analyze which approaches are appropriate, etc. She/he demonstrates ongoing very active involvement. Contributions in class reflect exceptional preparation. Ideas offered are always substantive, and provide one or more major insights as well as direction for the class. If this person were not a member of the class, the quality of discussion would be diminished markedly.
The average score out of the maximum of 4 is used to calculate the class participation score.
