  8. Chapter 5 Exercises: Part a (Exercises5a.pdf), Part b (Exercises5b.pdf).
  9. Examples Binomial Distribution Examples, Binomial Distribution Examples #2, Sample Proportion Examples, and Two Proportions Examples. Some examples are in multiple choice form which we do not adopt for the tests.
  10. Animated Demo for Normal Approximation of Binomial Distribution (normApprox4Binom.pdf): see how Binomial distribution becomes more like normal distribution with large sample size n. Download to view the animation, but do not print it. The control buttons are very much like those on a DVD player.
