The practise problems are posted already, but please notice, some of them are quite tough, only do them when you have extra time. You may go to MATH172 for help from the graders on Friday between 10:00-11:30am and 12:30-2:00 pm.
There are extra office hours from the graders: Friday 9:00 am - 11:00 am in MATH172

Course outline:
Chapters covered: 1-9
This is an applied statistics course for students with a calculus background (MA 162 or above). Probability theory is presented but applicable statistics is emphasized. Topics include: Probability, Random Variables and Probability Distributions, Point Estimation, Statistical Intervals, Tests of Hypotheses, Analysis of Variance, Simple Linear Regression etc.
Grading and exams:
Homework will be assigned most weeks. No late homework will be accepted no matter what the reason is. In return, two lowest homework scores will be dropped in case of emergency. There will be two evening midterms and one final exam. Students having exam conflicts or requesting special accommodations (documented) must inform the instructor as early as possible so that alternative plans may be arranged. Dates for the midterms:
Midterm I : 7th of Oct (up to 120 minutes) 8:00-10:00 pm PHYS 112
Midterm II: 11th of Nov(up to 120 minutes) 8:00-10:00 pm PHYS 112
Grade is calculated as: Homework 20%; Midterm I 20%; Midterm II 25%; Final 35%. The final scores will be curved and cutoffs of letter grades will be decided according to the final curve.
