Hello everyone,
Most of the multiple choice questions were taken from the reading and homework. So please go
through the chapters to solve any questions you have about those. If I made a mistake and the
book does not have the answer let me know and I’ll try and figure out where I went wrong.
Below are the answers to the open ended questions. Many of them are similar to homework
problems. Please learn the ones that you got wrong because the future material builds on the
beginning chapters so you may see some of this stuff again,
He spread of the exam scores was 12-30. The exam had a total of 31 possible points which
means each point is worth 3.22 %, I round up to the next whole number so 96.7% is 97%.
