a.
The final exams are graded and available on BS and the anon grades page.
b.
I have also attached the anon grades spreadsheet:
•
It contains your letter grades and you can explore the formulas I used to see how
they have been computed.
•
HW scaling to 200 is based on 10 minus 2 = 8 homeworks (since two were discarded)
•
Quiz scaling to 200 is based on 15 minus 3 = 12 quizzes (since three were discarded)
•
I have added a flat 40 points to everyone's score. Consider that your curved grade.
•
I have added an extra 5 points so that nobody will think they missed that next letter
grade by only one point.
You will lack at least SIX points!
•
Accordingly, don't try to bargain with me. You will not be successful!
•
I will migrate my course site intro my archive.
That should happen before Dec 20.
Once that is done, the link to its home page should be
Dr. Michael Fochler
http://people.math.binghamton.edu/mfochler/bu-mfx/bu-math-arv/math-447-2023-08/html/math-447-home.html

a.
I did quite a bit of work from home last Sunday which never made it to the server.
Affected are the following web pages:
•
course materials (quiz solutions + formula sheet)
•
schedule (Topics?)
•
grades (quiz 15?)
•
announcements
b.
I am still looking at the HW scores issue, but I think I understand what is going on:
•
My fault: When I updated my spreadsheet with the Cengage grades, I forgot to also
update the points possible for each HW assignment.
•
Their fault: Quite a few of you managed to get more than the max of 20
(after setting #2, 5, 6 to zero) on HW 12.
I will let those points stand.
c.
Stay put for an email with the newest version of the spreadsheet!
Should be less than an hour!
|
| 12/11/2023 |
I have changed the points of HW12 #2 from 6 to zero,
since two of you complained that this assignment wants to pull in an app
that does not exist under the URL given.
|
| 12/7/2023 |

| 11/25/2023 |
New WebAssign HW Math-447-2023-08-HW-11, due Mon Dec 4.
|
| 11/24/2023 |
New version 2023-11-24 of my lecture notes.
They now contain the material that corresponds to all of WMS Ch.6.
|
| 11/21/2023 |
Today's lecture will also be about Section 9.3
(The Method of Transformations in Multiple Dimension).
That's WMS Ch.6.6 (Multivariable Transformations Using Jacobians.
Quite a few of you seem to already have gone for the break.
Be very sure to study that material before next Monday's lecture.
It certainly will be on the final!
|

New version 2023-11-18 of my lecture notes.
They now contain the material that corresponds to
WMS Ch.6.2 - 6.4 and ch.6.6.

|
| 11/17/2023 |
a.
I am trying to accommodate both those who want to leave early for Thanksgiving
and those who will have a Math 346 midterm directly after this class.
•
I will give a QUIZ TODAY, but not at the end of the class.
•
Rather, this will be about 15 minutes into the lecture, depending on what is
a good time to interrupt lecturing.
|
| 11/14/2023 |
a.
I have published the midterm grades both on Brightspace and the grades page of my website.
Some welcome news: One of you noticed that two of the problems were about
joint random variables and not within the announced scope (nothing after WMS ch.4).
I have decided to give full credit to everyone for those problems.
That inflates your percentage. If you want to assess how well you were doing,
you should subtract 40 point from your grade and divide that by 150 - 40 = 110!
b.
I cannot return the exams to you today (Wed 11/14), since there will be a makeup quiz
after lecture.
c.
There will definitely be a quiz either this Friday or Monday next week
(Thanksgiving week).
d.
New WebAssign HW Math-447-2023-08-HW-10, due Wed Nov 29.
|
| 11/13/2023 |
a.
I have republished the formula sheet with the corrected variance for the
uniform distribution.
b.
Please do not leave your bags in the class room until I have placed the exams
and ask you to come in.
I would appreciate though, if you could separate the tables beforehand like in
the first midterm.
c.
Reminder: The exam starts at 11:45.
|
| 11/09/2023 |
a.
ERROR in the last line of the formula sheet:
I had specified the wrong MGF for the gamma distribution.
That has been corrected now.
I also fixed some benign typos like missing a parenthesis.
b.
There will be a quiz this Friday, Nov 10.
As promised, some of it will be relevant for Monday's midterm.
|
| 11/07/2023 |
a.
I have published the solutions for quiz 10 at the bottom of the course materials page.
b.
Start time for the Nov 13 exam will be 11:45. Duration is 60 minutes.
Scope: See the 10/23/2023 announcement.
c.
Question from one of your peers:
..... I am just confused on the grading system for quizzes because
if there’s 20 quizzes which are mostly out of 20 points and three get dropped,
can you still receive all 200 points even if you don’t get a 20/20 on every one?
Answer: That's complicated:
It is not clear at this point in time
how many quizzes will be given during this course.
Probably 14 or 15.
Each one will count the same (20 points) for the following reason:
Otherwise, it would be too difficult and contentious to determine
the three grades to be discarded.
The following will happen at the end:
•
Let us assume that n quizzes have been given.
•
I will scale your points to 200
by multiplying everyone's score by C := 200 / (20 (n-3) ).
•
Why? Let us assume that n=15. Assune that someone missed 2 quizzes
and got full 20 points on the other 13.
•
Then, after discarding the worst 3 quizzes,
that student got 12 * 20 = 240 points on the remaining n-3=12 quizzes.
•
That's a perfect score and it will be scaled to C*240 = 240*(200/240) = 200 points
•
On the other hand, if the best 12 quizzes amount to 60 points,
those will be scaled to C*60 = 60*(200/240) = 50 points.
•
For homework, I'll do something similar.
|
| 11/06/2023 |
I have published the grades of quiz 10.
I intend to publish the solutions tomorrow or Thursday.
|
| 10/28/2023 |
a.
I am communicating to you with great sadness that the student who was found dead
yesterday near the main library building was Natalia Malcevic,
one of the students in this class.
I have created
this document

It contains the Dateline announcement about Natalia's passing
and an email from Anna Jantz, a member of Harpur's CARE team.
The CARE team offers support to any student and staff member
who needs support when they are affected by traumatic events like this one.
b.
The

to give more time to those of you who have been emtionally impacted by Natalia's death.

c.
I am making an effort to update my lecture not with at least the definitions and
theorems of the WMS text.
That means that those chapters are subject to
continual changes until their material has been covered.
Accordingly, I have to renege on my promise
not to affect the references in my lecture notes

I had made a typo in problem #2 of quiz 2 (preimages):
I had written Z(x) = (Z + 3)2
instead of Z(x) = (x + 3)2.
This seems to have confused some of you.
I will rectify the situation as follows.
•
I'll add a similar problem to quiz #5, so study preimages!
•
If you score better on that one than on quiz 3 then I'll adjust
your quiz 3 score accordingly.
•
The date of quiz 5 will be Wed Sep 20.
•
I'll collect your quiz 3 today and/or Wednesday.
Please put it on my desk when you enter the room.
If you wait until I give quiz 5, that's too late!
|
| 9/16/2023 |

a.
I have posted the quiz 4 grades to BS and the anonymous grades to my grades page.
b.
By now some have reached their quota of 3 missed quizzes.
If you miss quizzes beyond that third one:
If you have a valid reason for your absence,
I will count a later quiz double for the one you missed. See syllabus.
If you are ill, no Dr's note is required; but you must have emailed me BEFORE
the start of EACH class you miss (or I will need that Dr's note).

About quiz #1 on Mon Aug 28:
•
I only lectured about ch.2.1 (Sets – The Basics), ch.2.2
(The Proper Use of Language in Mathematics: Any vs All, etc)
and ch.2.3 (Numbers), but the quiz will cover all of chapter 2.
•
Exception: You need not worry about the propositions, theorems and/or their proofs
if they are marked with the optional "*".
•
You need not recite definitions so marked
(but you may encounter a question that you cannot answer
if you do not understand such a definition).
•
I will cover the remaining material of ch.2 on Monday, before the quiz;
but it is better if you study it beforehand so you have time to digest it all.
|
| 8/24/2023 |
a.
I have updated the course materials page with a link to the Cengage web site for
this course.
If you click it you can access the e-text and do homework which will be graded by WebAssign.
