Here are some details on the exam:

  - It's during the usual class time, in the usual room.

  - It covers lecture, homework, and quizzes on chapters 5
    and 6 and sections 7.1 and 7.2.

  - It's closed book.

  - It requires a calculator.

  - You may bring two sheets of notes (8.5" by 11"), each
    with writing on both sides. I recommend writing on my
    posted formula sheets.

  - I'll provide the posted tables.

  - I'll hold an optional question & answer review session
    in Psychology 113 at 4:45 on Friday, April 12

Here are some studying steps I recommend:
  - Solve the homework and quiz problems as they're assigned.
  - Read the formula sheet. Figure out any formula you don't
    understand by studying the lecture notes or book. Add
    notes to the formula sheet as needed. (Some students add
    a few worked examples.)
  - Review the lecture notes.
  - Solve last semester's exam. (Your exam won't be the same.)
  - Solve additional odd problems from the book, checking
    your answers in the back.
  - Redo old quizzes. (Adding low scores to your quiz record
    doesn't change your high score, which is already recorded
    in Learn@UW.)

  Hi STAT 224 Students,
  
  While I'm glad to have tried a group-work approach to
  understanding power, I'm sorry to have let our schedule
  slip, so that I have to change what exam 2 will cover. Exam
  2 will cover chapters 5 and 6 and sections 7.1 and 7.2 (but
  not 7.3, 7.4, or 7.5, as originally planned). This causes a
  few messes:
  
  Regarding the posted formula sheet, formulas under the
  following headings are not required for exam 2:
    Small Samples with Normal X and Y (section 7.3)
    Matched Pairs (7.4)
    F Test for Equality of Variances (7.5)
    Simple Regression (8.1)
    Inference on Coefficients (8.1)
    Inference on Mean Response (8.1)
  Regarding the posted tables, the last one labeled "Upper
  Tail Points for the F Distributions" (7.5) is not required
  for exam 2. (I chose not to exclude these sections from the
  posted pages because they will be useful in their present
  forms for the final exam.)
  
  Regarding the posted "last semester's exam," the following
  problems are not models for your exam 2 (they may still be
  models for your final exam):
    #4 (section 7.3)
    #8 (section 7.5)
    #9 (section 7.4)
  
  Here is the posted homework due next Friday:
    F 4/12:
    6.7: 1-5,8,9
    Quiz 6
    7.1: 1,18,20
    7.2: 4,7,15,20,21
  (I'm mentioning this because there was a "..." instead of
  the 7.1 and 7.2 stuff for a day or two as I thought about
  what to do with exam 2.)
  
  All the best,
  
  John
  
  P.S. I posted filled-in notes for 6.6 and 6.7 under the
  "6.6" link.
