Chi-square distribution

June 26th, 2009

I’ve added a lesson to Section C.6 about the Chi-square distribution. It doesn’t come up very often on the exam, but is something that they are starting to ask about more frequently (basically going from 0 questions per exam to about 0.3 questions per exam over the past year).

I am also working on drafts of 3 more practice exams. I am hoping to get 2 of them posted next week (one earlier in the week, one later) and then the 3rd one early the following week.


More practice problems

June 15th, 2009

I’ve added a handful more practice problems to the problems for A.1 and A.2, along with a link to the video solutions to the problems (which you can also find at ) I haven’t yet recorded video solutions to the new problems, but will update the solutions file with the new problems when I do so.
