Your turn! Calculate the rest (Chi-Squared)

An in-class activity from the course slides — reproduced here so you can find it again after class.

📋 What to do

Slide for Your turn! Calculate the rest (Chi-Squared)
  1. The interval table is filled in for the first row only (0–100 hours).
  2. Calculate the rest: Fexp(t2), Fexp(t1), P-expected, and R-expected for each interval.
  3. Then calculate Chi-Squared for the goodness-of-fit test.

📮 Submit

Worked live in lesson, then answered as a pop quiz that opens on Canvas during class (1 pt) — graded on accuracy. The quiz uses a different data set than the one we fill in together, so run the procedure yourself. It appears in this week’s module on Canvas once your instructor opens it.

Note: work from this page — it is where the activity and its links (slide decks, shared materials) are maintained, and details may still be refined before class. Submission happens on Canvas, and so do the due date and your grade.
