,Preface
The purpose of Statistics for Business and Economics is to provide students, primarily in
the fields of business administration and economics, with a sound conceptual introduction
to the field of statistics and its many applications. The text is applications-oriented and has
been written with the needs of the nonmathematician in mind.
The solutions manual furnishes assistance by identifying learning objectives and providing
detailed solutions for all exercises in the text.
