STA 261s 2005

Introduction to Mathematical Statistics II

University of Toronto at Mississauga, Winter 2005

Lecture: Monday 11:10-12:00 p.m. and Wednesday 11:10-1:00 p.m., Room 1104, South Building

Tutorials: Wednesday 9:10-10:00 a.m. in Room 1161 and 10:10-11:00 a.m. in Room 1143, South Building

This page is now complete.

The marks I initially posted contained a serious calculation error for almost everyone. It has now been fixed. Please check again.

Here are the UNOFFCIAL Final exam scores and Marks. They are unofficial because professors do not assign final marks at the University of Toronto. We recommend marks to the department chair, who then decides what everyone gets (a quaint custom). These are the marks I am recommending.

I know it was hard. Just to survive STA261 this year was an accomplishment. In my eyes, a grade of C in this course is very respectable, and those who earned As and Bs have covered themselves with honour. Have a good summer!

     Number 12, like many probability problems that approach realism but are not about games of chance, is a bit messy. Please do it last. My answer is n=47. I used the quadratic formula to solve for sqrt(n). One comment about realism: a 1% chance that the plane will be overloaded is much too large. A 1% chance of being overloaded at least once in 500 flights would be better.

      

  3. Assignment 3: Read Sections 10.1-10.3 and do Exercises 10.1, 10.2, 10.5 through 10.11, 10.13 through 10.17, 10.23, 10.31 and 10.79. Quiz Wed. Jan. 26th.

      

  4. Assignment 4: Read Sections 10.4 and 10.5. You can read 10.6 if you wish, but we will not discuss robustness at this point and there will be no problems about it. Do Exercises 10.33 through 10.39, 10.41 through 10.44, 10.48, 10.49. For a hint about 10.44, see example 10.11 on page 333. Quiz Wed. Feb. 2nd.

      

  5. Assignment 5: Read Sections 10.7 and 10.8. Do Exercises 10.50 through 10.63, 10.66, 10.67, 10.69, and 10.71 through 10.73. Exercise 10.71 is particularly important; it is the basis of the most common method for testing whether there is an average difference between responses to a treatment and a control condition. We will refer to it later. Quiz on Wed. Feb 9th.
