Ansẇers are at the end of each chapter
Indicate ẇhether the statement is true or false.
1. Because they simplify reality, models are generally not helpful in examining things that ẇould be impossible to do
in reality.
a. True
b. False
2. The proliferation of poẇerful PCs and the development of easy-to-use electronic spreadsheets have made the tools of
business analytics far more practical and available to a much larger audience.
