Homework Assignments

Answers to odd-numbered problems are included in your textbook!

Instructions:

  • All homework problems are from your textbook.
  • Problems in BLACK color are hand-written 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 30-day trial (free) or 6-month 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.
