From most recent to earliest

---

• 08 Feb: Snow day: class for Friday is cancelled, and assignment 3 is now due on Tuesday, 12 Feb, paper or electronic, at class. No late hand-ins, we will post solutions on 12 February.
• 06 Feb: quite a few emails asking if enough information is provided in assignment 3, etc. General rule: if information isn't provided, and you think it should have been, use an assumed value, but clearly justify why you've assumed the value, and why you picked the value you did.
• 06 Feb: regarding question 2 and 3 in assignment 3: the problem is sufficiently specified, it is just not obvious what you need to do. That's typical ... an industrial statistics problem doesn't present itself to you in the form: "Calculate a confidence interval ...."; you have figure out what you want to determine (the aim), and then what you need to calculate. It is an important skill to learn how to translate an industrial requirement into a statistical calculation.
• 06 Feb: the weekly tests are going well so far, so the midterm for 4C3 is cancelled.
  • Expect the grading part of the website to be ready during reading week.
