Please
check
this page on a regular basis for updated announcements relating to the
course.
 Date: April 24,
2011
- I
have
posted solutions to HW 10
PRIOR
ANNOUNCEMENTS
Date: April 22,
2011
- Graded
HW
9
papers are in a white envelope outside my door; please pick them
up. There is also another envelope with older assignments that
were not picked up in class; you may want to pick these up as well.
- Please
make
sure
that you return the first two tests to me if you have not
already done so.
Date: April 20,
2011
- I
have
posted
solutions
to
HW
Assignment
9
as well as HW Assignment 10 on control charts. You need
not
hand in HW10 but do try to work on the questions - it will help you
prepare
for the test. I will post solutions early over the weekend.
- The
final
exam
will
be
at
2
PM
on Monday, April 25 in our regular classroom. Format will
be similar to the previous test: closed book/notes but I will allow you
one hand-written "crib sheet" - one side of an 8.5 by 11 inch sheet of
paper - which you will hand in with your test.
- You
are
responsible
for
all
material
covered
in
class. The primary focus will be on Chapters
7, 8 and 9 and the test will cover the following sections of the
text:
- Chapter
7: Everything
except the "bootstrap" stuff on page 261, the last two
subsections of 7.3
(on pages 275-276), and Section 7.4.
- Chapter 8: Everything
except for Sections 8.3 and 8.5. You may also skip all
the formulas
derived for b
(Type II error probability) and sample size (n) determination -
however, you should be clear on what b
represents and how it is generally defined and derived, as discussed in
the first section of the chapter.
- Chapter 9: Sections 9.1,
9.2 and 9.3 only - again, you may skip any formulas derived for b
and sample size (n).
- Chapter
16: Sections
16.1, 16.2, the S-chart (pages 637-638) in 16.3.
- Good
luck
on
all
your
final
exams
and
have a great summer!
Date: April 18,
2011
- Today's
lecture
is
canceled
- sorry for the late
announcement, but I have a personal emergency to attend to.
- I
will
be
handing
back
graded
HW
8
on Wednesday and also talking about
the final exam at that time.
- Talking
of
exams,
there
are
still
several
people
who havce not handed back
their two earlier tests to me - please
make
sure
that
I
get
these
back
by the end of the week!
Date: April 11,

30, 2011
- I
have
posted
solutions

HW7
that
you
handed
in
today.

the tests, please remember to hand them back to me.
- I
have
posted
HW8
on
tests
of
hypotheses;
this
is
due

start with the first few questions, but the rest of it will probably
need Monday's lecture.

11

continuous
distributions

Uniform,
Normal

- Solutions to
Assignment 2 have
also been posted for you to download.
- I will also be

try and get an early start

as well as the last one based on what we covered in class today)...
Date:
January 19,
2011
- MINITABTM (the statistics software
we will use in this class) is available in all the CSSD labs via the
university's
software network. If you wish to purchase a personal
license
through Software Licensing Services at Pitt you can do so at
virtually no cost (it's $5).
- Assignment 2 (due
Jan 26) has
been posted. Please start early because
it's
a
slightly
longer
one,
and
will
take
you
significantly
more
time
than
the
first
assignment.
- Starting with
this assignment,
I will be using a real-world data set as a case study throughout the
course
for illustrating various concepts, and also for you to analyze using MINITABTM.
A
description
of
this
data
set
may
be
found
in
the
Clark
data
set web page - please familiarize yourself with the contents of
this page. The actual data file may be downloaded from there,
either
as an Excel file or as a MINITABTM input file.
- Solutions to
Assignment 1 have
also been posted for you to download.
Date: January 10, 2011
- I
have
posted
HW
assignment
1;
this
is
due in on Wed., Jan 19 (since school is closed
Jan 17) and can
be downloaded from the Homework
Assignments page.
- I
forgot
to
mention
this
in
class
last week, but
please also bring your textbook to class since I will often work out
example
problems from the end of the chapter/section.
Date: January 5, 2011
- I
will
update
this
page
any
time
I
have
an
announcement
that
I
would
like
to
make
or
when
I
have
a
document
for
you
to
download
off
the
web - typically, these will be
homework
assignments and their solutions which can be obtained from the Homework
Assignments page.
- All
documents
will
be
made
available
as
Adobe
Acrobat
files
(with
a
.pdf extension). In some
instances,
documents might also be posted as MS-Excel files (when there are
spreadsheets)
or MINITAB data files. In order to download a document to your machine,
you may simply click on the filename. You may then print the document,
save it or do whatever else you wish with it.
- To
try
this
out
here
is
a
document
that
contains
the
course
outline
and
description:
course.pdf.
- I
have
collated
copies
of
most
of
the
Powerpoint
slides
that
I
use
for
this
class
and
put
them
together
into
the
Web Documents page. Please
browse
through these on a regular basis. Also, before coming to class,
please
print out the pages that relate to the next lecture (the schedule
should tell you what we will be covering next in class) and bring
these
copies with you to class. That way, you can listen to the lecture
and
take down any notes directly on the copies of the Powerpoint slides
that you have
(rather than frantically trying to copy everything you see on the
slides...).
