Handout
If you aren't comfortable with Z and T tests from another class, you may wish to try some extra problems, like 8, 10, or 17. You may also want to download the the inclass handout which may be easier to understand than section 10.5. - HW 5, due 2/28 (Solution)
9-27a, then for 2/50 and 25/50 successes, compute a 95% CI using both the traditional way and the way described in part b, using the answer in the back.
9-29, 9-31, 9-35, 9-37
Using data from 9-R11, calculate an ordinary 95% CI for theta, and then Bayesian 95% credible intervals for theta for the two priors shown. How do you interpret each of these intervals? Finally, assuming the true theta equals 4, what's the corresponding p-value? What if the true theta is 1? - HW 4, due 2/21 (Solution)
