Almeda, Capistrano and Sarte. Other References 1. Introduction to Statistics (3rd Edition). Walpole. 2. Introduction to Statistics and Probability. Mendenhall. Course Requirements Long Exams There will be 3 long exams for this course. The coverage of the exams is as follows: First Exam Second Exam Third Exam

Coverage Sections 1-9, 12 Sections 10-11 Sections 13-18

The three (3) long exams will be scheduled outside class hours. All exams are closed notes exams. Formula sheets will be provided only when necessary. If you missed an exam for valid reasons, see me as soon as possible and present the proper certification. Make-up exams (coverage: all chapters) will be given at the end of the semester. Final Exam The coverage of the final exam will be from Sections 1 – 18. This will be a test on how well you know the methods, concepts and their properties without requiring any hardcore computations. There will be no exemptions from the final exam. This is a departmental exam. The final exam will be on October 13, 2011 (Thursday) 8-12 nn. Attendance Attendance will be checked at the end of the class. The maximum number of excuses or unexcused absences is 6. In class, you are all expected to participate and to be attentive.
