HW due: Work on your group project. Important: Be sure to include the
names of your test subjects in your raw data table. If you have forgotten some
of them or did not record their names, include as many as you can remember.
If for privacy reasons (or simply lack of recordkeeping) you did not pair the
names of your subjects with their individual lines of data, that is OK, but
in that case, be sure to list as many names as you can remember beneath the
raw data table itself.

HW due:
1. Develop a methodology for a simulation to address the question below.
2. Execute your methodology for enough iterations to come up with a
reasonable estimate for the answer.
3. (Optional for bonus) Make a confidence interval for your estimate.
The specific rules for Game 2 will be e-mailed to you so that the problem is
slightly different for each student.
Question: What is the mean value
of Game 1?
The value of Game 1 is defined to be the outcome of a die roll, provided the
roll is 1, 2, 3, or 4. However, if the die comes up 5 or 6, then the value of
Game 1 is determined by performing a different game called “Game 2.” The
specific rules of Game 2 will be e-mailed to you. For purposes of
illustration below, suppose that Game 2 is defined by rolling the die again,
and if this new die roll is 3, 4,
5, or 6, then that is the value of the game; otherwise, the value of Game 2
equals whatever one gets by starting afresh with Game 1 (and another roll of
the die).
Clearly, this can get rather complicated! To understand what is going on,
please check out this sample tabulation.
Remember, we are not interested in the mean value of Game 2; we are
interested only in the mean value of Game 1.

Announcement:
Class will meet in MH-103 today and tomorrow.
HW due: At least six (6) AP multiple-choice problems, plus a 13- or 25-minute
free-response problem of your choice, either from the Barron’s review book or
from the College
Board website. Write all work on a separate sheet of paper, and indicate
page number and problem number for each problem. This assignment should take
you about half an hour. There is no need to log the points, since your sheet
will be scanned, along with your assignment for 4/27.

Announcement:
Class will meet in MH-103 again today.
HW due: Another six (6) AP multiple-choice problems, plus another 13- or
25-minute free-response problem of your choice. Write all work on a separate sheet
of paper, and indicate page number and problem number for each problem.
The in-class problem from yesterday will also be collected. If you missed it,
it is presented below, along with an altered version.
In-Class Problem:
A two-way table for a census of students from NDS (National Dentistry School)
is shown below. Is there any evidence of an association between smelliness
and nosiness? Test using  = 0.05, and show all
required steps (HATPC).
Altered Version of Problem (optional,
but recommended, especially for students planning to take the AP exam):
Repeat the in-class problem as above, except with a different table of data:

HW due:
1. (Required for everyone.) Complete the AP Review Problem handout.
Collaboration is permitted but is not recommended for those planning to take
the AP exam on Wednesday. Score will be based on neatness and completeness.
If you were absent Friday, be sure that you notice and understand all the
typographical corrections on the handout. Everyone is expected to complete
this assignment on time, because nobody was sick Friday. (Everyone who missed
either had a partial-day excuse or was granted leave in preparation for the
afternoon AP Euro exam. There is no need for a day of grace.)
2. (Optional, but strongly recommended for those who plan to take the AP
exam.) Do the alternate version of the smelliness/nosiness independence check
posted in last Friday’s calendar entry. This should take you less than 5
minutes. Note that n = 365 for both
versions of the problem, and df = 12 for both versions.
Tip and Jamie are excused from class today for AP Bio in the morning but
should still slip their HW papers under Mr. Hansen’s office door by 3:15 p.m.
Julian, Zeke, Andrei, Preston, and Andrew have AP Physics B or C in the
afternoon and can be excused from D period upon request. Send e-mail by
midnight Sunday, 5/8, if you wish to be excused from class, but be sure to
give your HW to Mr. Hansen (or slip it under the office door) before the
start of your afternoon exam.

HW due:
1. Finish your AP Review Problem
handout (all problems) if you have not already done so.
2. Then, do another 20 to 45 minutes’ worth of AP review problems from the
Barron’s book. Keep a time log, and show all work and problem numbers on a
separate sheet. If you are not taking the AP exam on Wednesday, you may
substitute Must-Pass Quiz
problems if you wish, since everyone
must pass the Must-Pass Quiz. If you are Chick, you may omit part 2 of the
assignment.

After class today, Nick S. and Daniel K. passed the
MPQ, joining Chick, Alex, Brennan, Julien (who passed during the field trip,
on the bus), Andrei, Edward, Justin, Phineas, Dominique, and Andrew in the
Winner’s Circle.
Still awaiting a passing score: Ousmane (starting round 5), Zeke (about
halfway through round 2, with 5/6 of a mulligan remaining), Tip (also halfway
through round 2, with about 1/4 of a mulligan remaining), Nick R.-S.
(starting round 1), Jordan (starting round 3), Preston (starting round 1),
and Jamie (starting round 3). If we maintain the recent pace of 2 passes per
day, everyone will be finished by the end of the week. That would be a
delightful state of affairs, since then everyone would be exempt from taking
the final exam on June 2.
