Chi-square distribution
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.
