The homework assignments on this page are organized by due dates. On most days you will have both a reading assignment, and a problem set. Unless we indicate otherwise, all readings come from your textbook, Statistics by Freedman, Pisani, and Purves. Furthermore, the current homework assignment (the one due during the next class meeting) will be highlighted by an orange title bar.

WORKSHEET HINTS (from the blitzes that were sent out today):

Message 1:

``` Here's a hint that might get you started if you are having trouble: The probability that a subject gets infected after having sex 120 times means you have to find the probability that the disease was transmitted AT LEAST once during those 120 trials (this should suggest the idea of using the complementary probability). ```

``` The formula we studied in class on Tuesday is useful when you have a certain "experiment" that is repeated over and over. There are three important variables, n, k, and p. It might be helpful when working on question 2 to consider what exactly your "experiment" is, what a success represents, and what the probability of a single success is. ```

Message 2:

``` Just to clarify questions 3 and 4 on the handout a little bit: we aren't asking for any calculations. We just want you to digest the numbers you've crunched and make some observations about them. ```

``` For question 4, you are asked if the "results" of the study seem reasonable to you. I am specifically referring to the fact that in this Italian study, 3 of 171 couples who always used condoms ended up with the woman becoming infected. The other result concerning couples who didn't always use condoms is included for the sake of completeness. Basically, part 2(d) asks you to compute the probability that if this study was done again, the results would be the same (or worse, in the sense that more women being infected is worse). Then, question 4 asks you to interpret the significance of that probability. ```

Study for the exam!
