A new blood test is highly sensitive, able to correctly detect the presence of ovarian cancer in 99.97% of women who have the disease. However, the false positive rate is 1% and hence the test is unlikely to be used as a screening test in the general population. Why are false positives such a big problem? Use both (i) a tree diagram and (ii) Bayes Rule to determine the probability that a woman who tests positive using this method actually has ovarian cancer. (4) Reminder: Test 2 is on Friday, May 9.

The following homework (which will be graded as two homeworks) is based on Wednesday and Friday's lab work and will be due next Monday.
(1) Read Chapters 23, 24, and 25 (2) Turn in all of the following problems. Unless noted, do all problems using S-PLUS. Include your computer output and give explanations where necessary. Answer the questions in the homework explicitly; do not merely rely on computer output alone. Page 596: 5, 12, 17, 20, 27 (do not compute the confidence interval by hand; just take the book's solution as given), 33, 34. Note that the data for problems 17 (hearing), 20 (meals), and 33 (colorortext) are on-line in Collab -> Departments -> MATH -> Statistics -> Math_215 -> Dobrow. Data for other problems need to be input into S-PLUS by hand. For each of the above inference problems clearly indicate in your solution whether the problem is (i) a one-sample procedure for proportions, (ii) two-sample procedure for proportions; (iii) one-sample for means; (iv) two independent groups for means; or (v) matched pairs for means. (3) Reminder: Set up a group meeting with me to discuss your final project. | Mon, 5/26 |
| 24 |
(1) Read about Benson's Law
(2) Read Chapter 26 (3) p 625: 1*, 3, 4*, 7, 13* (4) Wednesday's class is in the Lab. |
Wed, 5/28 |
| 25 | (1) Review
(2) See Lab Manual, pp 59-65. (3) No HW to be turned in. Use S-PLUS for 11, 15, 21. (4) For Friday's discussion (not to be turned in): Look at the even-numbered problems in the Part V and Part VI reviews. Do not do these problems (unless you want), but identify the type of inference being used in each. See the "Think" column on the Quick Guide to Inference (p 595). For each problem decide (i) what's the inference about? (ii) one group or two; and (iii) procedure. |
