Statistical Techniques in Business and Economics

This is an INSTRUCTOR'S ADDITION!I used it for a basic 2000 level major class, and it still matched perfectly with the books everyone else had. There was no difference, the ISBN just didn't match.I bought the book used from Amazon about 6 months ago. It has used stickers on it, and the four edges of the hardcover fold a little bit. I mailed it off once to a woman who decided to return it because it wasn't what she needed- and she broke the inside paper that covers the spine is folded back only about halfway down the inside of the cover page.
