Homework
Assignments
Answers to oddnumbered problems are
included in your textbook!
Instructions:
 All homework problems are
from your textbook.
 Problems in BLACK color are handwritten problems.
Problems in RED color
are Minitab problems, which need the use of Minitab to answer questions.
 To save paper, DO NOT print outputs/graphs directly from
Minitab! Please copy and paste Minitab outputs/graphs into
a Word document such that you
can edit and then print.
 Datasets can be found in
the book CD or downloaded from the Textbook
Companion Website. Please use Minitab Files (Format) or Text Files
(Format).
 Minitab is available on
most campus computers. Personal copies can be obtained via 30day
trial (free) or 6month rental (for $30). Please visit http://www.onthehub.com/minitab/
for more details.
 Minitab 18 for PC is a
full version, while Minitab Express for Mac is a light version. The
Minitab instructions provided with HW problems are based on Minitab for PC. If
you are using Minitab Express for Mac, the interface
is somewhat different from the one of Minitab for PC. You may either
explore and figure out by yourself or ask me for help.
